Languages like Lua and SQL use "--" to mark a line as commented out.
If this appears at column 0 and is part of the pre-image we may see
"--- foo" in the diff, indicating that the line whose content is
"-- foo" has been removed from the new version.
git-gui was incorrectly parsing "--- foo" as the old file name
in the file header, causing it to generate a bad patch file when
the user tried to stage or unstage a hunk or the selected line.
We need to keep track of where we are in the parsing so that we do
not misread a deletion or addition record as part of the header.

Assume that we want to commit these states:
Old state == HEAD Intermediate state New state

old 2 old 2 new 2
context after context after context after
that is, want to commit two changes in this order:
1. transform "old 1" into "new 1"
2. transform "old 2" into "new 2"
[This discussion and this patch is about this very case and one other case
as outlined below; any other intermediate states that one could imagine are
not affected by this patch.]
Now assume further, that we have not staged and commited anything, but we
have already changed the working file to the new state. Then we will see
this hunk in the "Unstaged Changes":
@@ -1,4 +1,4 @@
context before
-old 1
-old 2
+new 1

The obvious way to stage the intermediate state is to apply "Stage This
Line" to "-old 1" and "+new 1". Unfortunately, this resulted in this
intermediate state:
context before
old 2
new 1
context after
which is not what we wanted. In fact, it was impossible to stage the
intermediate state using "Stage Line". The crux was that if a "+" line was
staged, then the "-" lines were converted to context lines and arranged
*before* the "+" line in the forged hunk that we fed to 'git apply'.
With this patch we now treat "+" lines that are staged differently. In
particular, the "-" lines before the "+" block are moved *after* the
staged "+" line. Now it is possible to get the correct intermediate state
by staging "-old 1" and "+new 1". Problem solved.
But there is a catch.
Noticing that we didn't get the right intermediate state by staging
"-old 1" and "+new 1", we could have had the idea to stage the complete
hunk and to *unstage* "-old 2" and "+new 2". But... the result is the same.
The reason is that there is the exact symmetric problem with unstaging the
last "-" and "+" line that are in adjacent blocks of "-" and "+" lines.
This patch does *not* change the way in which "-" lines are *unstaged*.
Why? Because if we did (i.e. move "+" lines before the "-" line after
converting them to context lines), then it would be impossible to stage
this intermediate state:
context before
old 1
new 2
context after
that is, it would be impossible to stage the two independet changes in the
opposite order.
Let's look at this case a bit further: The obvious way to get this
intermediate state would be to apply "Stage This Line" to "-old 2" and
"+new 2". Before this patch, this worked as expected. With this patch, it
does not work as expected, but it can still be achieved by first staging
the entire hunk, then *unstaging* "-old 1" and "+new 1".
In summary, this patch makes a common case possible, at the expense that
a less common case is made more complicated for the user.

This adds a context menu entry below "Stage/Unstage Hunk" that stages or
unstages just the line under the mouse pointer.
This is by itself useful, for example, if there are unrelated changes in
the same hunk and the hunk cannot be split by reducing the context.
The feature can also be used to split a hunk by staging a number of
additions (or unstaging a number of removals) until there are enough
context lines that the hunk gets split.
The implementation reads the complete hunk that the line lives in, and
constructs a new hunk by picking existing context lines, removing unneeded
change lines and transforming other change lines to context lines. The
resulting hunk is fed through 'git apply' just like in the "Stage/Unstage
Hunk" case.

If we feed a bad dictionary name to aspell on startup it may appear
to start (as Tcl found the executable in our $PATH) but it fails to
give us the version string. In such a case the close of the pipe
will report the exit status of the process (failure) and that is
an error in Tcl.
We now trap the subprocess failure and display the stderr message
from it, letting the user know why the failure is happening. We then
disable the spell checker, but keep our object instance so the user
can alter their preferred dictionary through the options dialog, and
possibly restart the spell checker.
I was also originally wrong to use "error" here for the display
of the problem to the user. I meant to use "error_popup", which
will open a message box and show the failure in a GUI context,
rather than killing git-gui and showing the message on the console.

Many user friendly tools like word processors, email editors and web
browsers allow users to spell check the message they are writing
as they type it, making it easy to identify a common misspelling
of a word and correct it on the fly.
We now open a bi-directional pipe to Aspell and feed the message
text the user is editing off to the program about once every 300
milliseconds. This is frequent enough that the user sees the results
almost immediately, but is not so frequent as to cause significant
additional load on the system. If the user has modified the message
text during the last 300 milliseconds we delay until the next period,
ensuring that we avoid flooding the Aspell process with a lot of
text while the user is actively typing their message.
We wait to send the current message buffer to Aspell until the user
is at a word boundary, thus ensuring that we are not likely to ask
for misspelled word detection on a word that the user is actively
typing, as most words are misspelled when only partially typed,
even if the user has thus far typed it correctly.
Misspelled words are highlighted in red and are given an underline,
causing the word to stand out from the others in the buffer. This is
a very common user interface idiom for displaying misspelled words,
but differs from one platform to the next in slight variations.
For example the Mac OS X system prefers using a dashed red underline,
leaving the word in the original text color. Unfortunately the
control that Tk gives us over text display is not powerful enough
to handle such formatting so we have to work with the least common
denominator.
The top suggestions for a misspelling are saved in an array and
offered to the user when they right-click (or on the Mac ctrl-click)
a misspelled word. Selecting an entry from this menu will replace
the misspelling with the correction shown. Replacement is integrated
with the undo/redo stack so undoing a replacement will restore the
misspelled original text.
If Aspell could not be started during git-gui launch we silently eat
the error and run without spell checking support. This way users
who do not have Aspell in their $PATH can continue to use git-gui,
although they will not get the advanced spelling functionality.
If Aspell started successfully the version line and language are
shown in git-gui's about box, below the Tcl/Tk versions. This way
the user can verify the Aspell function has been activated.
If Aspell crashes while we are running we inform the user with an
error dialog and then disable Aspell entirely for the rest of this
git-gui session. This prevents us from fork-bombing the system
with Aspell instances that always crash when presented with the
current message text, should there be a bug in either Aspell or in
git-gui's output to it.
We escape all input lines with ^, as recommended by the Aspell manual
page, as this allows Aspell to properly ignore any input line that is
otherwise looking like a command (e.g. ! to enable terse output). By
using this escape however we need to correct all word offsets by -1 as
Aspell is apparently considering the ^ escape to be part of the line's
character count, but our Tk text widget obviously does not.
Available dictionaries are offered in the Options dialog, allowing
the user to select the language they want to spellcheck commit
messages with for the current repository, as well as the global
user setting that all repositories inherit.
Special thanks to Adam Flott for suggesting connecting git-gui
to Aspell for the purpose of spell checking the commit message,
and to Wincent Colaiuta for the idea to wait for a word boundary
before passing the message over for checking.

The code we use to test if a hook is executable or not differs on
Cygwin from the normal POSIX case. Rather then repeating that for
all three hooks we call in our commit code path we can place the
common logic into a global procedure and invoke it when necessary.
This also lets us get rid of the ugly "|& cat" we were using before
as we can now rely on the Tcl 8.4 feature of "2>@1" or fallback to
the "|& cat" when necessary.
The post-commit hook is now run through the same API, but its outcome
does not influence the commit status. As a result we now show any of
the errors from the post-commit hook in a dialog window, instead of on
the user's tty that was used to launch git-gui. This resolves a long

Under core Git the git-commit tool will invoke the commit-msg hook
if it exists and is executable to the user running git-commit. As
a hook it has some limited value as it cannot alter the commit, but
it can modify the message the user is attempting to commit. It is
also able to examine the message to ensure it conforms to some local
standards/conventions.
Since the hook takes the name of a temporary file holding the message
as its only parameter we need to move the code that creates the temp
file up earlier in our commit code path, and then pass through that
file name to the latest stage (where we call git-commit-tree). We let
the hook alter the file as it sees fit and we don't bother to look at
its content again until the commit succeeded and we need the subject
for the reflog update.

Often users setup a few source files and get a project rolling
before they create a Git repository for it. In such cases the
core Git tools allow users to initialize a new repository by
simply running `git init` at the desired root level directory.
We need to allow the same situation in git-gui; if the user is
trying to make a new repository we should let them do that to any
location they chose. If the directory already exists and already
has files contained within it we still should allow the user to
create a repository there. However we still need to disallow
creating a repository on top of an existing repository.
