Add support for 'show-sizes' feature to show (in separate column,
between mode and filename) the size of blobs (files) in the 'tree'
view.  It passes '-l' option to "git ls-tree" invocation.

For the 'tree' and 'commit' (submodule) entries, '-' is shown in place
of size; for generated '..' "up directory" entry nothing is shown.

The 'show-sizes' feature is enabled by default.

4a3da5d91a gitk: Show diff of commits at end of compare-commits output
When comparing a string of commits, when we find two non-merge commits
that differ, we now write the two commits to files and diff the files.
This pulls out the logic for creating a temporary directory from
external_diff into a separate procedure so that the new diffcommits
procedure can use it.

Because the diff command returns an exit status of 1 when the files
differ, and Tcl treats that as an error, this adds catch {} around the
close statements in getblobdiffline.

At present this only removes the temporary files when gitk exits.  It
should remove them when the diff is done.

7c9f7038e9 commit: support alternate status formats
The status command recently grew "short" and "porcelain"
options for alternate output formats. Since status is no
longer "commit --dry-run", these formats are inaccessible to
people who do want to see a dry-run in a parseable form.

This patch makes those formats available to "git commit",
implying the "dry-run" option when they are used.

6f15787181 status: add --porcelain output format
The "short" format was added to "git status" recently to
provide a less verbose way of looking at the same
information. This has two practical uses:

  1. Users who want a more dense display of the information.

  2. Scripts which want to parse the information and need a
     stable, easy-to-parse interface.

For now, the "--short" format covers both of those uses.
However, as time goes on, users of (1) may want additional
format tweaks, or for "git status" to change its behavior
based on configuration variables. Those wishes will be at
odds with (2), which wants to stability for scripts.

This patch introduces a separate --porcelain option early to
avoid problems later on.  Right now the --short and
--porcelain outputs are identical. However, as time goes on,
we will have the freedom to customize --short for human
consumption while keeping --porcelain stable.

aeb84b05ae core.whitespace: split trailing-space into blank-at-{eol,eof}
People who configured trailing-space depended on it to catch both extra
white space at the end of line, and extra blank lines at the end of file.
Earlier attempt to introduce only blank-at-eof gave them an escape hatch
to keep the old behaviour, but it is a regression until they explicitly
specify the new error class.

This introduces a blank-at-eol that only catches extra white space at the
end of line, and makes the traditional trailing-space a convenient synonym
to catch both blank-at-eol and blank-at-eof.  This way, people who used
trailing-space continue to catch both classes of errors.

0ef95f72f8 pack-objects: free preferred base memory after usage
When adding objects for preferred delta base, the content from tree
objects leading to given paths is kept in a cache. This has the
potential to grow significantly, especially with large directories as
the whole tree object content is loaded in memory, even if in practice
the number of those objects is limited to the 256 cache entries plus the
$window root tree objects.  Still, that can't hurt freeing that up after
object enumeration is done, and before more memory is needed for delta
search.

6523078b96 make shallow repository deepening more network efficient
First of all, I can't find any reason why thin pack generation is
explicitly disabled when dealing with a shallow repository.  The
possible delta base objects are collected from the edge commits which
are always obtained through history walking with the same shallow refs
as the client, Therefore the client is always going to have those base
objects available. So let's remove that restriction.

Then we can make shallow repository deepening much more efficient by
using the remote's unshallowed commits as edge commits to get preferred
base objects for thin pack generation.  On git.git, this makes the data
transfer for the deepening of a shallow repository from depth 1 to depth 2
around 134 KB instead of 3.68 MB.

couldn't easily color code the new blank lines at the end of file.

Reuse the adds_blank_at_eof() function to find where the runs of such
blank lines start, keep track of the line number in the preimage while
processing the patch output one line at a time, and paint the new blank
lines that appear after that line to implement this.

5b5061efd8 diff --whitespace=warn/error: obey blank-at-eof
The "diff --check" code used to conflate trailing-space whitespace error
class with this, but now we have a proper separate error class, we should
check it under blank-at-eof, not trailing-space.

The whitespace error is not about _having_ blank lines at end, but about
adding _new_ blank lines.  To keep the message consistent with what is
given by "git apply", call whitespace_error_string() to generate it,
instead of using a hardcoded custom message.

77b15bbd88 apply --whitespace=warn/error: diagnose blank at EOF
"git apply" strips new blank lines at EOF under --whitespace=fix option,
but neigher --whitespace=warn nor --whitespace=error paid any attention to
these errors.

Introduce a new whitespace error class, blank-at-eof, to make the
whitespace error handling more consistent.

The patch adds a new "linenr" field to the struct fragment in order to
record which line the hunk started in the input file, but this is needed
solely for reporting purposes.  The detection of this class of whitespace
errors cannot be done while parsing a patch like we do for all the other
classes of whitespace errors.  It instead has to wait until we find where
to apply the hunk, but at that point, we do not have an access to the
original line number in the input file anymore, hence the new field.

Depending on your point of view, this may be a bugfix that makes warn and
error in line with fix.  Or you could call it a new feature.  The line
between them is somewhat fuzzy in this case.

Strictly speaking, triggering more errors than before is a change in
behaviour that is not backward compatible, even though the reason for the
change is because the code was not checking for an error that it should
have.  People who do not want added blank lines at EOF to trigger an error
can disable the new error class.

efa574438f apply --whitespace=fix: detect new blank lines at eof correctly
The command tries to strip blank lines at the end of the file added by a
patch.  It is done by first detecting if a hunk in patch has additional
blank lines at the end of itself, and if so checking if such a hunk
applies at the end of file.  This patch addresses a bug in the logic to
implement the former (the previous one addressed a bug in the latter).

If the original ends with blank lines, often the patch hunk ends like
this:

    @@ -l,5 +m,7 @@$
    _context$
    _context$
    -deleted$
    +$
    +$
    +$
    _$
    _$

where _ stands for SP and $ shows a end-of-line.  This example patch adds
three trailing blank lines, but the code fails to notice it, because it
only pays attention to added blank lines at the very end of the hunk.  In
this example, the three added blank lines do not appear textually at the
end in the patch, even though you can see that they are indeed added at
the end, if you rearrange the diff like this:

    @@ -l,5 +m,7 @@$
    _context$
    _context$
    -deleted$
    _$
    _$
    +$

The fix is not to reset the number of (candidate) added blank lines at the
end when the loop sees a context line that is empty.

b94f2ed (builtin-apply.c: make it more line oriented, 2008-01-26) broke
the logic used to detect if a hunk adds blank lines at the end of the

 - img holds the contents of the file that the hunk is being applied to;

 - preimage has the lines the hunk expects to be in img; and

 - postimage has the lines the hunk wants to update the part in img that
   corresponds to preimage with.

and we need to compare if the last line of preimage (not postimage)
matches the last line of img to see if the hunk applies at the end of the
file.

12d4996622 clone: disconnect transport after fetching
The current code just leaves the transport in whatever state
it was in after performing the fetch.  For a non-empty clone
over the git protocol, the transport code already
disconnects at the end of the fetch.

But for an empty clone, we leave the connection hanging, and
eventually close the socket when clone exits. This causes
the remote upload-pack to complain "the remote end hung up
unexpectedly". While this message is harmless to the clone
itself, it is unnecessarily scary for a user to see and may
pollute git-daemon logs.

This patch just explicitly calls disconnect after we are
done with the remote end, which sends a flush packet to
upload-pack and cleanly disconnects, avoiding the error
message.

Other transports are unaffected or slightly improved:

 - for a non-empty repo over the git protocol, the second
   disconnect is a no-op (since we are no longer connected)

 - for "walker" transports (like HTTP or FTP), we actually
   free some used memory (which previously just sat until
   the clone process exits)

 - for "rsync", disconnect is always a no-op anyway

228e7b5d4d status: list unmerged files much later
When resolving a conflicted merge, two lists in the status output need
more attention from the user than other parts.

 - the list of updated paths is useful to review the amount of changes the
   merge brings in (the user cannot do much about them other than
   reviewing, though); and

 - the list of unmerged paths needs the most attention from the user; the
   user needs to resolve them in order to proceed.

Since the output of git status does not by default go through the pager,
the early parts of the output can scroll away at the top. It is better to
put the more important information near the bottom.  During a merge, local
changes that are not in the index are minimum, and you should keep the
untracked list small in any case, so moving the unmerged list from the top
of the output to immediately after the list of updated paths would give us
the optimum layout.

3c2eb80fe3 stash: simplify defaulting to "save" and reject unknown options
With the earlier DWIM patches, certain combination of options defaulted
to the "save" command correctly while certain equally valid combination
did not.  For example, "git stash -k" were Ok but "git stash -q -k" did
not work.

This makes the logic of defaulting to "save" much simpler. If there are no
non-flag arguments, it is clear that there is no command word, and we
default to "save" subcommand.  This rule prevents "git stash -q apply"
from quietly creating a stash with "apply" as the message.

This also teaches "git stash save" to reject an unknown option.  This is
to keep a mistyped "git stash save --quite" from creating a stash with a
message "--quite", and this safety is more important with the new logic
to default to "save" with any option-looking argument without an explicit
comand word.

[jc: this is based on Matthieu's 3-patch series, and a follow-up
discussion, and he and Peff take all the credit; if I have introduced bugs
while reworking, they are mine.]

c4ccf61f4c gitweb: Create links leading to 'blame_incremental' using JavaScript
The new 'blame_incremental' view requires JavaScript to run.  Not all
web browsers implement JavaScript (e.g. text browsers such as Lynx),
and not all users have JavaScript enabled.  Therefore instead of
unconditionally linking to 'blame_incremental' view, we use JavaScript
to convert those links to lead to view utilizing JavaScript, by adding
'js=1' to link.

Currently the only action that takes 'js=1' into account is 'blame',
which then acts as if it was called as 'blame_incremental' action.
Possible enhancement would be to do JavaScript redirect by setting
window.location instead of modifying $format and $action in
git_blame_common() subroutine.

The only JavaScript-aware/using view is currently 'blame_incremental'.
While at it move reading JavaScript to git_footer_html() subroutine.
Note that in this view we do not add 'js=1' currently (even though
perhaps we should; note that for consistency we should also add 'js=1'
in links added by JavaScript part of 'blame_incremental').

This idea was originally implemented by Petr Baudis in
  http://article.gmane.org/gmane.comp.version-control.git/47614
but it added <script> element with fixBlameLinks() function in page
header, to be added as onload event using 'onload' attribute of HTML
'body' element: <body onload="fixBlameLinks();">.  This version adds
script at then end of page (in the page footer), and uses JavaScript
'window.onload=fixLinks();'.  Also in Petr version only links marked
with 'blamelink' class were modified, and they were modified by
replacing "a=blame" by "a=blame_incremental"... which doesn't work for
path_info links, and might replace wrong part if there is "a=blame" in
project name, ref name or file name.

Slightly different solution was implemented by Martin Koegler in
  http://thread.gmane.org/gmane.comp.version-control.git/47902/focus=47905
Here GitAddLinks() function was in gitweb.js file, not as contents of
<script> element.  It was also included in page header (in <head>
element) though, which means waiting for a script to load (and run).
It was smarter in that to "fix" (modify) link, it split URL, modified
value of 'a' parameter, and then recreated modified link.  It avoids
trouble with "a=blame" as substring in project name or file name, but
it doesn't work with path_info URL/link in the way it was written.
