reasonably well because the SHA-1 hash has a fairly even distribution,

git-gui: Perform our own magic shbang detection on Windows
If we cannot locate a .exe for a git tool that we want to run than
it may just be a Bourne shell script as these are popular in Git.
In such a case the first line of the file will say "#!/bin/sh" so
a UNIX kernel knows what program to start to parse and run that.
But Windows doesn't support shbang lines, and neither does the Tcl
that comes with Cygwin.
We can pass control off to the git wrapper as that is a real Cygwin
program and can therefore start the Bourne shell script, but that is
at least two fork+exec calls to get the program running. One to do
the fork+exec of the git wrapper and another to start the Bourne shell
script. If the program is run multiple times it is rather expensive
as the magic shbang detection won't be cached across executions.
On MinGW/MSYS we don't have the luxury of such magic detection. The
MSYS team has taught some of this magic to the git wrapper, but again
its slower than it needs to be as the git wrapper must still go and
run the Bourne shell after it is called.

first line of the file and building our own command line path from
it. Currently we support Bourne shell (sh), Perl and Python. That

of remotes layout where all of their tracking branches are in
refs/remotes and refs/heads contains only the user's own local
branches.
In such a situation we can avoid calling is_tracking_branch

the heads must be local branches if no fetch option or Pull:

git-gui: Teach class system to support [$this cmd] syntax
Its handy to be able to ask an object to do something for you by
handing it a subcommand. For example if we want to get the value
of an object's private field the object could expose a method that
would return that value. Application level code can then invoke
"$inst get" to perform the method call.
Tk uses this pattern for all of its widgets, so we'd certainly
like to use it for our own mega-widgets that we might develop.
Up until now we haven't needed such functionality, but I'm working
on a new revision picker mega-widget that would benefit from it.
To make this work we have to change the definition of $this to
actually be a procedure within the namespace. By making $this a
procedure any caller that has $this can call subcommands by passing
them as the first argument to $this. That subcommand then needs
to call the proper subroutine.
Placing the dispatch procedure into the object's variable namespace
ensures that it will always be deleted when the object is deleted.

c:\cygwin\share directory, as that is where it should be relative
to the script itself in c:\cygwin\bin.
In my first version of this patch I tried to use `cygpath` to resolve
/usr/bin and /usr/share to test that they were in the same relative
locations, but that didn't work out correctly as we were actually

always used relative paths. So my original solution was quite wrong.

interest, but not usually.
We now show the original commit data first in the tooltip. This

current file (no -M -C -C) as that set of annotations tells us who
put the hunk here (who moved/copied it). I'm now calling the -M
-C -C pass "original location annotations" as that's what we're
really digging for.
I also tried to clarify some of the text in the hover tooltip.

git-gui: Use three colors for the blame viewer background
To prevent neighboring lines that are different commits from using
the same background color we now use 3 colors and assign them
by selecting the color that is not used before or after the line
in question. We still color "on the fly" as we receive hunks from
git-blame, but we delay our color decisions until we are getting
the original location data (the slower -M -C -C pass) as that is
usually more fine-grained than the current location data.
Credit goes to Martin Waitz for the tri-coloring concept.

git-gui: Jump to original line in blame viewer
When the user clicks on a commit link within one of the columns
in the blame viewer we now jump them not just to that commit/file
pair but also to the line of the original file. This saves the
user a lot of time, as they don't need to search through the new
file data for the chunk they were previously looking at.
We also restore the prior view when the user clicks the back button
to return to a pior commit/file pair that they were looking at.
Turned out this was quite tricky to get working in Tk. Every time
I tried to jump the text widgets to the correct locations by way
of the "yview moveto" or "see" subcommands Tk performed the change
until the current event finished dispatching, and then reset the
views back to 0, making the change never take place. Forcing Tk
to run the pending events before we jump the UI resolves the issue.

git-gui: Run blame twice on the same file and display both outputs
We now perform two passes over any input file given to the blame
viewer. Our first pass is a quick "git-blame" with no options,
getting the details of how each line arrived into this file. We
are specifically ignoring/omitting the rename detection logic as
this first pass is to determine why things got into the state they
are in.
Once the first pass is complete and is displayed in the UI we run
a second pass, using the much more CPU intensive "-M -C -C" options
to perform extensive rename/movement detection. The output of this
second pass is shown in a different column, allowing the user to see
for any given line how it got to be, and if it came from somewhere
else, where that is.
This is actually very instructive when run on our own lib/branch.tcl
script. That file grew recently out of a very large block of code
in git-gui.sh. The first pass shows when I created that file, while
the second pass shows the original commit information.

git-gui: Rename fields in blame viewer to better descriptions
Calling the commit message pane $w_cmit is a tad confusing when
we also have the $w_cgrp column that shows the abbreviated SHA-1s.
So w_cmit -> w_cviewer, as it is the "commit viewer"; and
w_cgrp -> w_amov as it is the "annotated commit + move tracking"
column. Also changed line_data -> amov_data, as that list is
exactly the results shown in w_amov.
Why call the column "move tracking"? Because this column holds
data from "git blame -M -C". I'm considering adding an additional
column that holds the data from "git blame" without -M/-C, showing
who did the copy/move, and when they did it.

git-gui: Switch internal blame structure to Tcl lists
The Tcl list datatype is significantly faster to work with than
the array type, especially if our indexes are a consecutive set
of numbers, like say line numbers in a file.
This rather large change reorganizes the internal data structure
of the blame viewer to use a proper Tcl list for the annotation
information about a line. Each line is given its own list within
the larger line_data list, where the indexes correspond to various
facts about that particular line.
The interface does seem to be more responsive this way, with less
time required by Tcl to process blame, and to switch to another
version of the same file. It could just be a placebo effect, but
either way most Tcl experts perfer lists for this type of work over
arrays.

Originally I had placed this loaded column between the line number

received annotation data or not yet. This way users would know if
the line(s) they were interested in were ready for viewing, or if
they still had to wait. It also was an entertaining way for the
user to spend their time waiting for git-blame --incremental to
compute the complete set of annotations.
However it is completely useless now that we show the abbreviated
commit SHA-1 and author initials in the leftmost column. That area
is empty until we get the annotation data, and as soon as we get it
in we display something there, indicating to the user that there is
now blame data ready. Further with the tooltips the user is likely
to see the data as soon as it comes in, as they are probably not
keeping their mouse perfectly still. So I'm removing the field to
save screen space for more useful things, like file content.
