e59903fb01 Merge 'git-wrapper' into HEAD
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.

e6faa23ee8 Merge 'aslr' into HEAD
Address Space Layout Randomization (ASLR) allows executables' memory
layout to change at random between runs, and therefore offers a quite
decent protection against many attacks.

We enable ASLR because MSYS2's C compiler offers support for ASLR, and
whatever performance impact it has is neglible, according to
https://insights.sei.cmu.edu/cert/2014/02/differences-between-aslr-on-windows-and-linux.html

23fd91e8a1 Do not mask the username when reading credentials
When user is asked for credentials there is no need to mask username,
so PROMPT_ASKPASS flag on calling credential_ask_one for login is
unnecessary.

credential_ask_one internally uses git_prompt which in case of given
flag PROMPT_ASKPASS uses masked input method instead of
git_terminal_prompt, which does not mask user input.

9d93c12a3f Fix initial git gui message encoding
This fix refers https://github.com/git-for-windows/git/issues/664

After `git merge --squash` git creates .git/SQUASH_MSG (UTF-8 encoded)
which contains squashed commits. When run `git gui` it copies SQUASH_MSG
to PREPARE_COMMIT_MSG, but without honoring UTF-8. This leads to encoding
problems on `git gui` commit prompt.

The same applies on git cherry-pick conflict, where MERGE_MSG is created
and then is copied to PREPARE_COMMIT_MSG.

In both cases PREPARE_COMMIT_MSG must be configured to store data in UTF-8.

86cad11ca0 gitk: make the "list references" default window width wider
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.

9a1a516c8b git-wrapper: do not let the Ctrl-C event kill the wrapper
... 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.]

7da46c682c pull: allow interactive rebase with --rebase=interactive
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.

98b719a5ae git-wrapper: fix interpolation with short values
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.

out of the way first, to avoid overwriting them with the interpolated
text.

5dee72b1fd git-wrapper: append $HOME/bin to the PATH
`$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).

d3032bcc2e git-wrapper: support COMSPEC better
The quoting rules of `cmd.exe` are really, really quirky. In particular,
if there are more than two quotes, the entire set of rules changes. That
is the reason why

	CMD /C "C:\Program Files\Git\usr\bin\bash.exe" -l -i

works, but

	CMD /C "C:\Program Files\Git\usr\bin\bash.exe" -l -i "test.sh"

fails with this error message:

	'C:\Program' is not recognized as an internal or external command,
	operable program or batch file.

The recommended fix is to pass the /S option to `cmd.exe` and surround
the entire command-line by an extra set of quotes. And here lies the
rub: for that to work, we have to append an extra quote. At the end of
the command-line. *After* the last argument was appended, if any.

This commit supports that use case by introducing the option
"APPEND_QUOTE". The intended usage is to use the following string
resource:

	SHOW_CONSOLE=1 APPEND_QUOTE=1
	@@COMSPEC@@ /S /C \"\"@@EXEPATH@@\\usr\\bin\\bash.exe\" --login -i

(Note that there are only three quotes on that command-line, the fourth
to be appended due to the `APPEND_QUOTE` setting.)

e47569b21c mingw: let the Git wrapper determine the top-level directory
The Git wrapper is also used as a redirector for Git for Windows'
bin\bash.exe dropin: for backwards-compatibility, bin\bash.exe exists
and simply sets up the environment variables before executing the
*real* bash.

However, due to our logic to use the directory in which the `.exe`
lives as top-level directory (or one directory below for certain, known
basenames such as `git.exe` and `gitk.exe`), the `PATH` environment
variable was prefixed with the `/bin/bin` and `/bin/mingw/bin`
directories -- which makes no sense.

Instead, let's just auto-detect the top-level directory in the common
case.

dde58d4068 git-wrapper: leave the working directory alone by default
The idea of `git-bash.exe` automatically running the Git Bash in the
home directory was to support the start menu item `Git Bash` (which
should not start in C:\Program Files\Git, but in $HOME), and to make
that behavior consistent with double-clicking in `git-bash.exe`
portable Git.

However, it turns out that one of the main use cases of portable Git is
to run the Git Bash in GitHub for Windows, and it should start in the
top-level directory of a given project. Therefore, the concern to keep
double-clicking `git-bash.exe` consistent with the start menu item was
actually unfounded.

As to the start menu item: it can easily be changed to launch
`git-bash.exe` with a command-line option. So let's introduce the
--cd-to-home option for that purpose.

As a bonus, the Git wrapper can now also serve as a drop-in redirector
/bin/bash.exe to provide backwards-compatibility of Git for Windows 2.x
with 1.x: some 3rd-party software expects to find that executable there,
and it also expects it to leave the working directory unchanged.

211ac797e7 git-wrapper: allow overriding the command to spawn via command-line args
By embedding string resources into the Git wrapper executable, it
can be configured to execute custom commands (after setting up the
environment in the way required for Git for Windows to work properly).
This feature is used e.g. for `git-bash.exe` which launches a Bash in
the configured terminal window.

Here, we introduce command-line options to override those string
resources. That way, a user can call `git-bash.exe` (which is a copy of
the Git wrapper with `usr\bin\bash.exe --login -i` embedded as string
resource) with command-line options that will override what command is
run.

ConEmu, for example, might want to call

	...\git-bash.exe --needs-console --no-hide --minimal-search-path ^
		--command=usr\\bin\\bash.exe --login -i

In particular, the following options are supported now:

--command=<command-line>::
	Executes `<command-line>` instead of the embedded string resource

--[no-]minimal-search-path::
	Ensures that only `/cmd/` is added to the `PATH` instead of
	`/mingw??/bin` and `/usr/bin/`, or not

--[no-]needs-console::
	Ensures that there is a Win32 console associated with the spawned
	process, or not

--[no-]hide::
	Hides the console window, or not
