840bcfa7b5 git-gui: Bind M1-P to push action
Users often need to be able to push the current branch so that they
can publish their recent changes to anyone they are collaborating
with on the project.  Associating a keyboard action with this will
make it easier for keyboard-oriented users to quickly activate the
push features.

7aecb12877 git-gui: properly popup error if gitk should be started but is not installed
On 'Visualize ...', a gitk process is started.  Since it is run in the
background, catching a possible startup error doesn't work, and the error
output goes to the console git-gui is started from.  The most probable
startup error is that gitk is not installed; so before trying to start,
check for the existence of the gitk program, and popup an error message
unless it's found.

This was noticed and reported by Paul Wise through
 http://bugs.debian.org/429810

7e508eb1a2 git-gui: Don't require a .pvcsrc to create Tools/Migrate menu hack
The Tools/Migrate menu option is a hack just for me.  Yes, that's
right, git-gui has a hidden feature that really only works for me,
and the users that I support within my day-job's great firewall.
The menu option is not supported outside of that environment.

In the past we only enabled Tools/Migrate if our special local
script 'gui-miga' existed in the proper location, and if there
was a special '.pvcsrc' in the top level of the working directory.
This latter test for the '.pvcsrc' file is now failing, as the file
was removed from all Git repositories due to changes made to other
tooling within the great firewall's realm.

I have changed the test to only work on Cygwin, and only if the
special 'gui-miga' is present.  This works around the configuration
changes made recently within the great firewall's realm, but really
this entire Tools/Migrate thing should be abstracted out into some
sort of plugin system so other users can extend git-gui as they need.

4e817d1ac4 git-gui: Don't require $DISPLAY just to get --version
Junio asked that we don't force the user to have a valid X11 server
configured in $DISPLAY just to obtain the output of `git gui version`.
This makes sense, the user may be an automated tool that is running
without an X server available to it, such as a build script or other
sort of package management system.  Or it might just be a user working
in a non-GUI environment and wondering "what version of git-gui do I
have installed?".

Tcl has a lot of warts, but one of its better ones is that a comment
can be continued to the next line by escaping the LF that would have
ended the comment using a backslash-LF sequence.  In the past we have
used this trick to escape away the 'exec wish' that is actually a Bourne
shell script and keep Tcl from executing it.

I'm using that feature here to comment out the Bourne shell script and
hide it from the Tcl engine.  Except now our Bourne shell script is a
few lines long and checks to see if it should print the version, or not.

39fa2a983d git-gui: Save geometry before the window layout is damaged
Because Tk does not assure us the order that it will process
children in before it destroys the main toplevel we cannot safely
save our geometry data during a "bind . <Destroy>" event binding.
The geometry may have already changed as a result of a one or
more children being removed from the layout.  This was pointed
out in gitk by Mark Levedahl, and patched over there by commit
b6047c5a81.

So we now also use "wm protocol . WM_DELETE_WINDOW" to detect when
the window is closed by the user, and forward that close event to
our main do_quit routine.

b2f3bb1b66 git-gui: Give amend precedence to HEAD over MERGE_MSG
Apparently git-commit.sh (the command line commit user interface in
core Git) always gives precedence to the prior commit's message if
`commit --amend` is used and a $GIT_DIR/MERGE_MSG file also exists.

We actually were doing the same here in git-gui, but the amended
message got lost if $GIT_DIR/MERGE_MSG already existed because
we started a rescan immediately after loading the prior commit's
body into the edit buffer.  When that happened the rescan found
MERGE_MSG existed and replaced the commit message buffer with the
contents of that file.  This meant the user never saw us pick up
the commit message of the prior commit we are about to replace.

Johannes Sixt <J.Sixt@eudaptics.com> found this bug in git-gui by
running `git cherry-pick -n $someid` and then trying to amend the
prior commit in git-gui, thus combining the contents of $someid
with the contents of HEAD, and reusing the commit message of HEAD,
not $someid.  With the recent changes to make cherry-pick use the
$GIT_DIR/MERGE_MSG file Johannes saw git-gui pick up the message
of $someid, not HEAD.  Now we always use HEAD if we are amending.

debcd0fd02 git-gui: Display the "Loading annotation..." message in italic
If the user clicks on a line region that we haven't yet received
an annotation for from git-blame we show them "Loading annotation".
But I don't want the user to confuse this loading message with a
commit whose first line is "Loading annotation" and think we messed
up our display somehow.  Since we never use italics for anything
else, I'm going with the idea that italic slant can be used to show
data is missing/elided out at the time being.

For quite a while we have been assuming the user is running on
a Tcl/Tk 8.4 or later platform.  This may not be the case on
some very old systems.  Unfortunately I am pretty far down the
path of using the Tcl/Tk 8.4 commands and options and cannot
easily work around them to support earlier versions of Tcl/Tk.
So we'll check that we are using the correct version up front,
and if not we'll stop with a related error message.

fc4e8da727 git-gui: Internalize symbolic-ref HEAD reading logic
To improve performance on fork+exec impoverished systems (such as
Windows) we want to avoid running git-symbolic-ref on every rescan
if we can do so.  A quick way to implement such an avoidance is to
just read the HEAD ref ourselves; we'll either see it as a symref
(starts with "ref: ") or we'll see it as a detached head (40 hex
digits).  In either case we can treat that as our current branch.

aa252f194b git-gui: Allow users to delete remote branches
Git has supported remote branch deletion for quite some time, but
I've just never gotten around to supporting it in git-gui.  Some
workflows have users push short-term branches to some remote Git
repository, then delete them a few days/weeks later when that topic
has been fully merged into the main trunk.  Typically in that style
of workflow the user will want to remove the branches they created.

We now offer a "Delete..." option in the Push menu, right below the
generic "Push..." option.  When the user opens our generic delete
dialog they can select a preconfigured remote, or enter a random
URL.  We run `git ls-remote $url` to obtain the list of branches and
tags known there, and offer this list in a listbox for the user to
select one or more from.

Like our local branch delete dialog we offer the user a way to filter
their selected branch list down to only those branches that have been
merged into another branch.  This is a very common operation as the
user will likely want to select a range of topic branches, but only
delete them if they have been merged into some sort of common trunk.

Unfortunately our remote merge base detection is not nearly as strict
as the local branch version.  We only offer remote heads as the test
commit (not any local ones) and we require that all necessary commits
to successfully run git-merge-base are available locally.  If one or
more is missing we suggest that the user run a fetch first.

Since the Git remote protocol doesn't let us specify what the tested
commit was when we evaluated our decision to execute the remote delete
there is a race condition here.  The user could do a merge test against
the trunk, determine a topic branch was fully merged, but before they
can start pushing the delete request another user could fast-forward
the remote topic branch to a new commit that is not merged into the
trunk.  The delete will arrive after, and remove the topic, even though
it was not fully merged.

61f82ce79a git-gui: Allow users to rename branches through 'branch -m'
Git's native command line interface has had branch renaming
support for quite a while, through the -m/-M options to the
git-branch command line tool.  This is an extremely useful
feature as users may decide that the name of their current
branch is not an adequate description, or was just entered
incorrectly when it was created.

Even though most people would consider git-branch to be a
Porcelain tool I'm using it here in git-gui as it is the
only code that implements the rather complex set of logic
needed to successfully rename a branch in Git.  Currently
that is along the lines of:

 *) Backup the ref
 *) Backup the reflog
 *) Delete the old ref
 *) Create the new ref
 *) Move the backed up reflog to the new ref
 *) Record the rename event in the reflog
 *) If the current branch was renamed, update HEAD
 *) If HEAD changed, record the rename event in the HEAD reflog
 *) Rename the [branch "$name"] section in the config file

Since that is some rather ugly set of functionality to implement
and get right, and some of it isn't easily accessible through the
raw plumbing layer I'm just cheating by relying on the Porcelain.

5b6ffff644 git-gui: GUI support for running 'git remote prune <name>'
In some workflows it is common for a large number of temporary
branches to be created in a remote repository, get fetched to
clients that typically only use git-gui, and then later have
those branches deleted from the remote repository once they have
been fully merged into all destination branches.  Users of git-gui
would obviously like to have their local tracking branches cleaned
up for them, otherwise their local tracking branch namespace would
grow out of control.

The best known way to remove these tracking branches is to run
"git remote prune <remotename>".  Even though it is more of a
Porcelain command than plumbing I'm invoking it through the UI,
because frankly I don't see a reason to reimplement its ls-remote
output filtering and config file parsing.

A new configuration option (gui.pruneduringfetch) can be used to
automatically enable running "git remote prune <remotename>" after
the fetch of that remote also completes successfully.  This is off
by default as it require an additional network connection and is
not very fast on Cygwin if a large number of tracking branches have
been removed (due to the 2 fork+exec calls per branch).

ea75ee3598 git-gui: Guess our share/git-gui/lib path at runtime if possible
Johannes Sixt asked me to try to avoid embedding the runtime location
of git-gui's library directory in the executable script.  Not embedding
it helps the MinGW to be relocatable to another directory should a user
wish to install the programs in a directory other than the location the
packager wanted them to be installed into.

Most of this is a hack.  We try to determine if the path of our master
git-gui script will be able to locate the lib by ../share/git-gui/lib.
This should be true if $(gitexecdir) and $(libdir) have the same prefix.
If they do then we defer the assignment of $(libdir) until runtime, and
we get it from $argv0 rather than embedding it into the script itself.

b9e7efb8b5 git-gui: Gracefully handle bad TCL_PATH at compile time

now if git-gui 0.7.0-rc1 or later is being used and TCL_PATH was not

a working build configuration today and suddenly upgrade to the latest
git release.

The tclIndex is required for git-gui to load its associated lib files,
but using the Tcl auto_load procedure to source only the files we need
is a performance optimization.  We can emulate the auto_load by just
source'ing every file in that directory, assuming we source class.tcl
first to initialize our crude class system.

exists in the working directory, otherwise we assume the argument
is a revision name.  A -- can be supplied between the two to force
parsing, or before the filename to force it to be a filename.

f522c9b5ed git-gui: Refactor into multiple files to save my sanity
I'm finding it difficult to work with a 6,000+ line Tcl script
and not go insane while looking for a particular block of code.
Since most of the program is organized into different units of
functionality and not all users will need all units immediately
on startup we can improve things by splitting procs out into
multiple files and let auto_load handle things for us.

This should help not only to better organize the source, but
it may also improve startup times for some users as the Tcl
parser does not need to read as much script before it can show
the UI.  In many cases the user can avoid reading at least half
of git-gui now.

Unfortunately we now need a library directory in our runtime
location.  This is currently assumed to be $(sharedir)/git-gui/lib
and its expected that the Makefile invoker will setup some sort of
reasonable sharedir value for us, or let us assume its going to be
$(gitexecdir)/../share.

We now also require a tclsh (in TCL_PATH) to just run the Makefile,
as we use tclsh to generate the tclIndex for our lib directory.  I'm
hoping this is not an unncessary burden on end-users who are building
from source.

I haven't really made any functionality changes here, this is just a
huge migration of code from one file to many smaller files.  All of
the new changes are to setup the library path and install the library
files.

f20db5ff30 git-gui: Correctly handle UTF-8 encoded commit messages
Uwe Kleine-König discovered git-gui mangled his surname and did
not send the proper UTF-8 byte sequence to git-commit-tree when
his name appeared in the commit message (e.g. Signed-Off-By line).

Turns out this was related to other trouble that I had in the past
with trying to use "fconfigure $fd -encoding $enc" to select the
stream encoding and let Tcl's IO engine do all of the encoding work
for us.  Other parts of git-gui were just always setting the file
channels to "-encoding binary" and then performing the encoding
work themselves using "encoding convertfrom" and "convertto", as
that was the only way I could make UTF-8 filenames work properly.

I found this same bug in the amend code path, and in the blame
display.  So its fixed in all three locations (commit creation,
reloading message for amend, viewing  message in blame).

outside of a Git repository to determine what version of git-gui was

We now look to see if the only argument we have been given is
'version' or '--version', and if so, print out the version and
exit immediately; long before we consider looking at the Git
version or working directory.  This way users can still get to
the git-gui version number even if Git's version cannot be read.

51bd9d7b8c git-gui: Don't create empty (same tree as parent) commits.
Mark Levedahl noticed that git-gui will let you create an empty
normal (non-merge) commit if the file state in the index is out
of whack.  The case Mark was looking at was with the new autoCRLF
feature in git enabled and is actually somewhat difficult to create.

I found a different way to create an empty commit:  turn on the
Trust File Modifications flag, touch a file, rescan, then move
the file into the "Changes To Be Committed" list without looking
at the file's diff.  This makes git-gui think there are files
staged for commit, yet the update-index call did nothing other
than refresh the stat information for the affected file.  In
this case git-gui allowed the user to make a commit that did
not actually change anything in the repository.

Creating empty commits is usually a pointless operation; rarely
does it record useful information.  More often than not an empty
commit is actually an indication that the user did not properly
update their index prior to commit.  We should help the user out
by detecting this possible mistake and guiding them through it,
rather than blindly recording it.

After we get the new tree name back from write-tree we compare
it to the parent commit's tree; if they are the same string and
this is a normal (non-merge, non-amend) commit then something
fishy is going on.  The user is making an empty commit, but they
most likely don't want to do that.  We now pop an informational
dialog and start a rescan, aborting the commit.

Because we bypassed main window UI setup to enter blame mode we
did not set many of the globals which were accessed by reshow_diff,
and reading unset variables is an error in Tcl.

Aside from moving the globals to be set earlier, I also modified
reshow_diff to not invoke clear_diff if there is no path currently

There actually are early releases of 1.5 (e.g. 1.5.0-rc0) that

these are purely academic at this point.  1.5.0 final was tagged

they want while the tool is running, we jump to the first line

at the very top of the file.

Since it takes a second (at least on my PowerBook) to even generate
the first annotation for git-gui.sh, the user should have plenty of
time to adjust the scrollbar or click on a line even before we get
that first annotation record in, which allows the user to bypass

6910ae80d0 git-gui: Redesign the display of annotated files.
Using 180 columns worth of screen space to display just 20 columns of
file data and 160 columns worth of annotation information is not
practically useful.  Users need/want to see the file data, and have
the anotation associated with it displayed in a detail pane only when
they have focused on a particular region of the file.

Now our file viewer has a small 10-line high pane below the file
which shows the commit message for the commit this line was blamed
on.  The columns have all been removed, except the current line
number column as that has some real value when trying to locate an
interesting block.

To keep the user entertained we have a progress meter in the status
bar of the viewer which lets them know how many lines have been
annotated, and how much has been completed.  We use a grey background
on the line numbers for lines which we have obtained annotation from,
and we color all lines in the current commit with a yellow background,
so they stand out when scanning through the file.  All other lines
are kept with a white background, making the yellow really pop.

One user that I spoke with recently was confused why the 'Add All'

The particular files in question were new, and thus not known to
Git.  Since the 'Add All' routine only updates files which are
already tracked, they were not added automatically.

Viewing annotated files is one of those tasks that is relatively
difficult to do in a simple vt100 terminal emulator.  The user

and to interact with it by navigating through revisions.

Now users can start our file viewer with annotations by running
'git gui blame commit path', thereby seeing the contents of the

Users want to navigate the file list shown in our branch browser

with the arrow keys:

  Return:   Move into the subtree, or open the annotated file.
  M1-Right: Ditto.

  M1-Up:    Move to the parent tree.
  M1-Left:  Ditto.

Probably the only feature missing from this is to key a leading part
of the file name and jump directly to that file (or subtree).

logic out of the mouse click procedure and into more generic routines
which can also be used in bindings.

icon which we already had.  I really need to replace the file_dir and
file_uplevel icons with something more useful.

If the user double clicks on a file within the browser we open it in
a blame viewer.  This makes use of the new incremental blame feature
that Linus just added yesterday to core Git.  Fortunately the feature
will be in 1.5.0 final so we can rely on having it available here.

Since the blame engine is incremental the user will get blame data
for groups which can be determined early.  Git will slowly fill in
the remaining lines as it goes.

20ddfcaa7e git-gui: Test for Cygwin differently than from Windows.
Running on Cygwin is different than if we were running through MinGW.

In the Cygwin case we have cygpath available to us, we need to perform
UNIX<->Windows path translation sometimes, and we need to perform odd
things like spawning our own login shells to perform network operations.
But in the MinGW case these don't occur.  Git knows native Windows file
paths, and login shells may not even exist.

Now git-gui will avoid running cygpath unless it knows its on Cygwin.
It also uses a different shortcut type when Cygwin is not present, and
it avoids invoking /bin/sh to execute hooks if Cygwin is not present.
This latter part probably needs more testing in the MinGW case.

This change also improves how we start gitk.  If the user is on any type
of Windows system its known that gitk won't start right if ~/.gitk exists.
So we delete it before starting if we are running on any type of Windows
operating system.  We always use the same wish executable which launched
git-gui to start gitk; this way on Windows we don't have to jump back to
/bin/sh just to go into the first wish found in the user's PATH.  This
should help on MinGW when we probably don't want to spawn a shell just
to start gitk.

accurate for the user's configuration.  If not then we try to guess
based on the operating system and the available browsers for each.
We prefer documentation which is installed parallel to Git's own

that is how I typically install the HTML docs.  If those are not found
then we open the documentation published on kernel.org.

In the same vein I've also added merge.verbosity to the gui options,

use that, but level 2 is the core Git default right now so we'll use

To allow users to merge local heads and tracking branches we now offer
a dialog which lets the user select 1-15 branches and merge them using
the stock `git merge` Grand Unified Merge Driver.

Originally I had wanted to implement this merge internally within git-gui
as I consider GUMD to be mostly Porcelain-ish, but the truth is it does
its job exceedingly well and its a relatively complex chunk of code.
I'll probably circle back later and try to remove the invocation of GUMD
from git-gui, but right now it lets me get the job done faster.

Users cannot start a merge if they are currently in the middle of one,
or if they are amending a commit.  Trying to do either is just stupid
and should be stopped as early as possible.

I've also made it simple for users to startup a gitk session prior to
a merge by offering a Visualize button which runs `gitk $revs --not HEAD`,
where $revs is the list of branches currently selected in the merge
dialog.  This makes it quite simple to find out what the damage will
be to the current branch if you were to carry out the currently proposed
merge.

A new procedure console_done can be passed to the last console_exec

23effa79f7 git-gui: Force focus to the diff viewer on mouse click.
Apparently a "feature" of Tcl/Tk on Mac OS X is that a disabled text
widget cannot receive focus or receive a selection within it.  This
makes the diff viewer almost useless on that platform as you cannot
select individual parts of the buffer.

Now we force focus into the diff viewer when its clicked on with
button 1.  This works around the feature and allows selection to
work within the viewer just like it does on other less sane systems,
like Microsoft Windows.

4e55d19a13 git-gui: Cleanup end-of-line whitespace in commit messages.
When committing changes its useless to have trailing whitespace on the
end of a line within the commit message itself; this serves no purpose
beyond wasting space in the repository.  But it happens a lot on my
Mac OS X system if I copy text out of a Terminal.app window and paste
it into git-gui.

We now clip any trailing whitespace from the commit buffer when loading
it from a file, when saving it out to our backup file, or when making
the actual commit object.

I also fixed a bug where we lost the commit message buffer if you quit
without editing the text region.  This can happen if you quit and restart
git-gui frequently in the middle of an editing session.

30b14ed390 git-gui: Elide CRs appearing in diff output from display.
If we are displaying a diff for a DOS-style (CRLF) formatted file then
the Tk text widget would normally show the CR at the end of every line;
in most fonts this will come out as a square box.  Rather than showing
this character we'll tag it with a tag which forces the character to
be elided away, so its not displayed.  However since the character is
still within the text buffer we can still obtain it and supply it over
to `git apply` when staging or unstaging an individual hunk, ensuring
that the file contents is always fully preserved as-is.

a25c518933 git-gui: Allow staging/unstaging individual diff hunks.
Just like `git-add --interactive` we can now stage and unstage individual
hunks within a file, rather than the entire file at once.  This works
on the basic idea of scanning backwards from the mouse position to
find the hunk header, then going forwards to find the end of the hunk.
Everything in that is sent to `git apply --cached`, prefixed by the
diff header lines.

We ignore whitespace errors while applying a hunk, as we expect the
user's pre-commit hook to catch any possible problems. This matches
our existing behavior with regards to adding an entire file with
no whitespace error checking.

Applying hunks means that we now have to capture and save the diff header
lines, rather than chucking them.  Not really a big deal, we just needed
a new global to hang onto that current header information.  We probably
could have recreated it on demand during apply_hunk but that would mean
we need to implement all of the funny rules about how to encode weird
path names (e.g. ones containing LF) into a diff header so that the
`git apply` process would understand what we are asking it to do.  Much
simpler to just store this small amount of data in a global and replay
it when needed.

I'm making absolutely no attempt to correct the line numbers on the
remaining hunk headers after one hunk has been applied.  This may
cause some hunks to fail, as the position information would not be
correct.  Users can always refresh the current diff before applying a
failing hunk to work around the issue.  Perhaps if we ever implement
hunk splitting we could also fix the remaining hunk headers.

Applying hunks directly means that we need to process the diff data in
binary, rather than using the system encoding and an automatic linefeed
translation.  This ensures that CRLF formatted files will be able to be
fed directly to `git apply` without failures.  Unfortunately it also means
we will see CRs show up in the GUI as ugly little boxes at the end of
each line in a CRLF file.

If the user selects a different branch from the Branch menu, or asks
us to create a new branch and immediately checkout that branch we
now perform the update of the working directory by way of a 2 way
read-tree invocation.

This emulates the behavior of `git checkout branch` or the behavior
of `git checkout -b branch initrev`.  We don't however support the
-m style behavior, where a switch can occur with file level merging
performed by merge-recursive.  Support for this is planned for a

0fd49d0a7d git-gui: Display database stats (count-objects -v) on demand.
Its nice to know how many loose objects and roughly how much disk space
they are taking up, so that you can guestimate about when might be a
good time to run 'Compress Database'.  The same is true of packfiles,
especially once the automatic keep-pack code in git-fetch starts to
be more widely used.

We now offer the output of count-objects -v in a nice little dialog
hung off the Repository menu.  Our labels are slightly more verbose
than those of `count-objects -v`, so users will hopefully be able
to make better sense of what we are showing them here.

We probably should also offer pack file size information, and data
about *.idx files which exist which lack corresponding *.pack files
(a situation caused by the HTTP fetch client).  But in the latter
case we should only offer the data once we have way to let the user
clean up old and inactive index files.

59885273c3 git-gui: Handle commit encoding better.
Git prefers that all log messages are encoding in UTF-8.  So now when
git-gui generates the commit message it converts the commit message
text from the internal Tcl Unicode representation into a UTF-8 file.
The file is then fed as stdin to git-commit-tree.  I had to start
using a file here rather than feeding the message in with << as
<< uses the system encoding, which we may not want.

When we reload a commit message via git-cat-file we are getting the
raw byte stream, with no encoding performed by Git itself.  So unless
the new 'encoding' header appears in the message we should probably
assume it is utf-8 encoded; but if the header is present we need to
use whatever it claims.

51a989ba5a git-gui: Honor system encoding for filenames.
Since git operates on filenames using the operating system encoding
any data we are receiving from it by way of a pipe, or sending to it
by way of a pipe must be formatted in that encoding.  This should
be the same as the Tcl system encoding, as its the encoding that
applications should be using to converse with the operating system.

Sadly this does not fix the gitweb/test file in git.git on Macs;
that's due to something really broken happening in the filesystem.

Users may want to know what a file is before they add it to the
repository, especially if its a binary file.  So when possible
invoke 'file' on the path and try to get its output.  Since
this is strictly advice to the user we won't bother to report
any failures from our attempt to run `file`.

Since some file commands also output the path name they were
given we look for that case and strip it off the front of the
returned output before placing it into the diff viewer.

19b41e4559 git-gui: Limit display of large untracked files.
Our internal diff viewer displays untracked files to help users see if
they should become tracked, or not.  It is not meant as a full file
viewer that handles any sort of input.  Consequently it is rather
unreasonable for users to expect us to show them very large files.
Some users may click on a very big file (and not know its very big)
then get surprised when Tk takes a long time to load the content and
render it, especially if their memory is tight and their OS starts to
swap processes out.

Instead we now limit the amount of data we load to the first 128 KiB
of any untracked file.  If the file is larger than 128 KiB we display
a warning message at the top of our diff viewer to notify the user
that we are not going to load the entire thing.  Users should be able
to recognize a file just by its first 128 KiB and determine if it
should be added to the repository or not.

Since we are loading 128 KiB we may as well scan it to see if the
file is binary.  So I've removed the "first 8000 bytes" rule and
just allowed git-gui to scan the entire data chunk that it read in.
This is probably faster anyway if Tcl's [string range] command winds
up making a copy of the data.

464c9ffee4 git-gui: Don't show content of untracked binary files.
A binary file can be very large, and showing the complete content of
one is horribly ugly and confusing.  So we now use the same rule that
core Git uses; if there is a NUL byte (\0) within the first 8000 bytes
of the file we assume it is binary and refuse to show the content.

Given that we have loaded the entire content of the file into memory
we probably could just afford to search the whole thing, but we also
probably should not load multi-megabyte binary files either.

124355d32c git-gui: Always start a rescan on an empty diff.
If we got an empty diff its probably because the modification time of
the file was changed but the file content hasn't been changed.  Typically
this happens because an outside program modified the file and git-gui
was told to not run 'update-index --refresh', as the user generally
trusts file modification timestamps.  But we can also get an empty diff
when a program undos a file change and still updates the modification
timestamp upon saving, but has undone the file back to the same as what
is in the index or in PARENT.

So even if gui.trustmtime is false we should still run a rescan on
an empty diff.  This change also lets us cleanup the dialog message
that we show when this case occurs, as its no longer got anything to
do with Trust File Modification Timestamps.
