git-gui: Correct 'git gui blame' in a subdirectory
David Kastrup pointed out that the following sequence was not
working as we had intended:
$ cd lib
$ git gui blame console.tcl
fatal: cannot stat path lib/console.tcl: No such file or directory
The problem here was we disabled the chdir to the root of the
working tree when we are running with a "bare allowed" feature
such as blame or browser, but we still kept the prefix we found via
`git rev-parse --show-prefix`. This caused us to try and look for
the file "console.tcl" within the subdirectory but also include
the subdirectory's own path from the root of the working tree.
This is unlikely to succeed, unless the user just happened to have
a "lib/lib/console.tcl" file in the repository, in which case we
would produce the wrong result.
In the case of a bare repository we shouldn't get back a value from
`rev-parse --show-prefix`, so really $_prefix should only be set
to the non-empty string if we are in a working tree and we are in a
subdirectory of that working tree. If this is true we really want
to always be at the top level of the working tree, as all paths are
accessed as though they were relative to the top of the working tree.
Converting $_prefix to a ../ sequence is a fairly simple approach
to moving up the requisite levels.

If the tclsh command was not available to us at the time we were

some of our library code now depends upon the git-version proc,

git-gui: Factor out common fast-forward merge case
In both the ff and reset merge_types supported by checkout_op the

git-gui: Automatically backup the user's commit buffer
A few users have been seeing crashes in Tk when using the undo key
binding to undo the last few keystroke events in the commit buffer.
Unfortunately that means the user loses their commit message and
must start over from scratch when the user restarts the process.
git-gui now saves the user's commit message buffer every couple of
seconds to a temporary file under .git (specifically .git/GITGUI_BCK).
At exit time we rename this file to .git/GITGUI_MSG if there is a
message, the file exists, and it is currently synchronized with the
Tk buffer. Otherwise we do our usual routine of saving the Tk buffer
to .git/GITGUI_MSG and delete .git/GITGUI_BCK, if it exists.
During startup we favor .git/GITGUI_BCK over .git/GITGUI_MSG. This
way a crash doesn't take out the user's message buffer but instead
will cause the user to lose only a few keystrokes. Most people do
not type more than 200 WPM, and with 30 possible saves per minute
we are unlikely to lose more than 7 words.

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.

git-gui: Default selection to first matching ref
If we have specifications listed in our revision picker mega-widget
then we should default the selection within that widget to the first
ref available. This way the user does not need to use the spacebar
to activate the selection of a ref within the box; instead they can
navigate up/down with the arrow keys and be done with it.

git-gui: Unabbreviate commit SHA-1s prior to display
If the end-user feeds us an abbreviated SHA-1 on the command line for
`git gui browser` or `git gui blame` we now unabbreviate the value

git-gui: Refactor branch switch to support detached head
This is a major rewrite of the way we perform switching between
branches and the subsequent update of the working directory. Like
core Git we now use a single code path to perform all changes: our
new checkout_op class. We also use it for branch creation/update
as it integrates the tracking branch fetch process along with a
very basic merge (fast-forward and reset only currently).
Because some users have literally hundreds of local branches we
use the standard revision picker (with its branch filtering tool)
to select the local branch, rather than keeping all of the local
branches in the Branch menu. The branch menu listing out all of
the available branches is simply not sane for those types of huge
repositories.
Users can now checkout a detached head by ticking off the option
in the checkout dialog. This option is off by default for the
obvious reason, but it can be easily enabled for any local branch
by simply checking it. We also detach the head if any non local
branch was selected, or if a revision expression was entered.

git-gui: Refactor our ui_status_value update technique
I'm really starting to dislike global variables. The ui_status_value
global varible is just one of those that seems to appear in a lot of
code and in many cases we didn't even declare it "global" within the
proc that updates it so we haven't always been getting all of the
updates we expected to see.
This change introduces two new global procs:
ui_status $msg; # Sets the status bar to show $msg.
ui_ready; # Changes the status bar to show "Ready."
The second (special) form is used because we often update the area
with this message once we are done processing a block of work and
want the user to know we have completed it.
I'm not fixing the cases that appear in lib/branch.tcl right now
as I'm actually in the middle of a huge refactoring of that code
to support making a detached HEAD checkout.

git-gui: Better handling of detached HEAD
If the current branch is not a symbolic-ref that points to a
name in the refs/heads/ namespace we now just assume that the
head is a detached head. In this case we return the special
branch name of HEAD rather than empty string, as HEAD is a
valid revision specification and the empty string is not.
I have also slightly improved the current-branch function by
using string functions to parse the symbolic-ref data. This
should be slightly faster than using a regsub. I think the
code is clearer too.

git-gui: Option to default new branches to match tracking branches
In some workflows users will want to almost always just create a new

it is handy to have the new branch dialog default to "Match Tracking

the branch filter field. This can save users working on this type
of workflow at least two mouse clicks every time they create a new
local branch or switch to one with a fast-forward.

git-gui: Sort tags descending by tagger date
When trying to create a branch from a tag most people are looking
for a recent tag, not one that is ancient history. Rather than
sorting tags by their string we now sort them by taggerdate, as

old ones at the end. Tag date works nicely as an approximation
of the actual history order of commits.

git-gui: Enhance choose_rev to handle hundreds of branches
One of my production repositories has hundreds of remote tracking
branches. Trying to navigate these through a popup menu is just
not possible. The list is far larger than the screen and it does
not scroll fast enough to efficiently select a branch name when
trying to create a branch or delete a branch.
This is major rewrite of the revision chooser mega-widget. We
now use a single listbox for all three major types of named refs
(heads, tracking branches, tags) and a radio button group to pick
which of those namespaces should be shown in the listbox. A filter
field is shown to the right allowing the end-user to key in a glob
specification to filter the list they are viewing. The filter is
always taken as substring, so we assume * both starts and ends the
pattern the user wanted but otherwise treat it as a glob pattern.
This new picker works out really nicely. What used to take me at
least a minute to find and select a branch now takes mere seconds.

git-gui: Fast-forward existing branch in branch create dialog
If the user elects to create a local branch that has the same name
as an existing branch and we can fast-forward the local branch to
the selected revision we might as well do the fast-forward for the
user, rather than making them first switch to the branch then merge
the selected revision into it. After all, its really just a fast
forward. No history is lost. The resulting branch checkout may
also be faster if the branch we are switching from is closer to
the new revision.
Likewise we also now allow the user to reset the local branch if
it already exists but would not fast-forward. However before we
do the actual reset we tell the user what commits they are going to
lose by showing the oneline subject and abbreviated sha1, and we also
let them inspect the range of commits in gitk.

git-gui: Optimize for newstyle refs/remotes layout
Most people using Git 1.5.x and later are using the newer style
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
for each head we are considering because we know that all of
the heads must be local branches if no fetch option or Pull:
line maps a branch into that namespace.
If however any remote maps a remote branch into a local
tracking branch that resides in refs/heads we do exactly
what we did before, which requires scanning through all
fetch lines in case any patterns are matched.
I also switched some regexp/regsub calls to string match
as this can be a faster operation for prefix matching.
