This fixes an issue where the Git wrapper would terminate upon Ctrl+C,
even in the case when its child process would *not* terminate.
Note: while the original intention was to fix running Git Bash in
ConsoleZ, the bug fix applies also to running
C:\Program Files\Git\bin\bash -l -i
in a cmd window.

"git pull --rebase" has been extended to allow invoking
"rebase -i".
* js/pull-rebase-i:
completion: add missing branch.*.rebase values
remote: handle the config setting branch.*.rebase=interactive
pull: allow interactive rebase with --rebase=interactive

There was a bug in the wrapper where it would interpolate incorrectly if
the name of the environment variable to expand was longer than the value.

Use msysGit's `git-wrapper` instead of the builtins. This works around
two issues:
- when the file system does not allow hard links, we would waste over
800 megabyte by having 109 copies of a multi-megabyte executable
- even when the file system allows hard links, the Windows Explorer
counts the disk usage as if it did not. Many users complained about
Git for Windows using too much space (when it actually did not). We
can easily avoid those user complaints by merging this branch.

This branch introduces support for reading the "Windows-wide" Git
configuration from `%PROGRAMDATA%\Git\config`. As these settings are
intended to be shared between *all* Git-related software, that config
file takes an even lower precedence than `$(prefix)/etc/gitconfig`.

These fixes were necessary for Sverre Rabbelier's remote-hg to work,
but for some magic reason they are not necessary for the current

When using remotes (with git-flow especially), the remote reference names
are almost always wordwrapped in the "list references" window because it's
somewhat narrow by default. It's possible to resize it with a mouse,
but it's annoying to have to do this every time, especially on Windows 10,
where the window border seems to be only one (1) pixel wide, thus making
the grabbing of the window border tricky.

... while waiting for the child process to finish.
The Git wrapper serves, among other things, as git-cmd.exe. In that
role, its primary purpose is to provide an interactive cmd window that
knows where to find Git.
A secondary use of git-cmd.exe is to be able to launch other console
processes that know about Git, e.g. when ConsoleZ wants to call an
interactive Bash (it cannot call git-bash.exe because that would open a
new MinTTY window). To this end, git-cmd.exe supports the --command=...
command-line option. The interactive bash would be called like this:
git-cmd --command=usr\bin\bash.exe -l -i
The command-line arguments after the --command=... options are simply
passed through to the command itself. If no --command=... option is
specified, git-cmd.exe defaults to cmd.exe.
Once git-cmd.exe is launched, it finds the top-level directory of the
Git for Windows installation and then launches the command as a child
process. And this is where things get a little bit tricky: When the user
presses CTRL-C, the cmd window receives WM_KEYDOWN/WM_KEYUP messages
which are then handled by the TranslateMessage function that generates a
CTRL-C event that is sent to the console processes running in the
console window (i.e. both git-cmd.exe and the child process).
If no Console Ctrl Handlers have been registered, the git-cmd.exe
process will simply be terminated, without having waited for the
interactive Bash to quit (it does not quit, of course, because it
handles Ctrl+C by terminating any process launched from within the
Bash). Now both cmd and the Bash compete for user input.
Luckily, the solution is very easy: the Win32 API sports a
SetConsoleCtrlHandler() function to register/unregister Console Ctrl
Handlers. When the NULL pointer is registered as "handler", it "causes
the calling process to ignore CTRL+C input":
https://msdn.microsoft.com/en-us/library/windows/desktop/ms686016.aspx
This is exactly what we need here: while waiting for the child processes
to finish, the git-cmd.exe process itself should not be interruptible by
the user. Immediately after the child process terminates, we unregister
the Console Ctrl Handler.
Note: we need to be careful with changes to the Git wrapper as it serves
many other purposes in addition to git-cmd.exe. For example, it serves
as the cmd\git.exe as well as all of the git-<builtin>.exe stand-ins.
So do we want the same Ctrl+C behavior even in those instances? Yes: If
the user interrupts using Ctrl+C, the child process should terminate
before the Git wrapper.
Also note: We cannot override the Console Ctrl Handler with a function
that simply always returns TRUE: this would prevent the console window
opened via git-cmd.exe from closing, since the Console Ctrl Handler
*also* handles "signals generated by the system when the user closes the
console, logs off, or shuts down the system."
[jes: changed the patch to conform with the surrounding coding style, to
pass NULL as Console Ctrl Handler and unregister it as soon as
appropriate, fixed commit message to be more accurate and informative,
added link to the SetConsoleCtrlHandler() documentation.]

Tcl/Tk 8.6 introduced new events for the cursor left/right keys and
apparently changed the behavior of the previous event.
Let's work around that by using the new events when we are running with
Tcl/Tk 8.6 or later.

In particular on Windows, where the default maximum path length is quite
small, but there are ways to circumvent that limit in many cases, it is
very important that users be given an indication why their command
failed because of too long paths when it did.
This test case makes sure that a warning is issued that would have
helped the user who reported Git for Windows' issue 521:

The config variable branch.<branchname>.rebase is not only used by `git
pull`, but also by `git remote` when showing details about a remote.
Therefore, it needs to be taught to accept the newly-introduced
`interactive` value of said variable.

A couple of years ago, I found the need to collaborate on topic
branches that were rebased all the time, and I really needed to see
what I was rebasing when pulling, so I introduced an
interactively-rebasing pull.
The way builtin pull works, this change also supports the value
'interactive' for the 'branch.<name>.rebase' config variable, which
is a neat thing because users can now configure given branches for
interactively-rebasing pulls without having to type out the complete
`--rebase=interactive` option every time they pull.

To be precise: when the value of the environment variable is shorter than
its name, we have to move the remaining bytes *after* expanding the
environment variable: we would look for the wrong name otherwise.
When the value is longer than the name, we still need to move the bytes
out of the way first, to avoid overwriting them with the interpolated
text.

variable to interpolate differ in length), we introduce a variable to
unclutter the code and make it more obvious what is happening.

After we found the `@@` marker after the key to interpolate, we pretty
much only need the offset *after* the marker. So let's just advance it

`$HOME/bin/` is quite convenient a place to put user-specific Git
helpers, such as credential or remote helpers.
When run in Git Bash, it is therefore already appended to the PATH;
Let's do the equivalent when run in Git CMD: when `git.exe` is
called, Git is told to look also for scripts and programs in
`$HOME/bin` (this does not modify Git CMD's `PATH`, of course).
