d2da9b0cd1 git-wrapper: simplify interpolation code
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
instead of adding 2 in many places.

1b7cdd371d git-gui (Windows): use git-bash.exe if it is available
Git for Windows 2.x ships with an executable that starts the Git Bash
with all the environment variables and what not properly set up. It is
also adjusted according to the Terminal emulator option chosen when
installing Git for Windows (while `bash.exe --login -i` would always
launch with Windows' default console).

So let's use that executable (usually C:\Program Files\Git\git-bash.exe)
instead of `bash.exe --login -i` if its presence was detected.

This fixes https://github.com/git-for-windows/git/issues/490

5dbb56c98f getpwuid(mingw): provide a better default for the user name

to load DLLs only when, and if, needed.

e99d19e6a9 t5813: do not use UNC paths
In Windows, a double slash in the beginning of an absolute path denotes
network paths of the form `\\localhost\share\file`. In Git for Windows'
context, the same form is also available with forward slashes.

Let's not start the path in the URL with a double slash (e.g.
`ssh://host//usr/src/git/t/file`) but take pains to use the normalized
form with a single slash, so that Git is not confusing the path for a
UNC one.

1cd20311b7 mmap(win32): avoid copy-on-write when it is unnecessary
Often we are mmap()ing read-only. In those cases, it is wasteful to map in

95069b35b1 win32mmap: set errno appropriately
It is not really helpful when a `git fetch` fails with the message:

	fatal: mmap failed: No error

In the particular instance encountered by a colleague of yours truly,
the Win32 error code was ERROR_COMMITMENT_LIMIT which means that the
page file is not big enough.

Let's make the message

	fatal: mmap failed: File too large

instead, which is only marginally better, but which can be associated
with the appropriate work-around: setting `core.packedGitWindowSize` to
a relatively small value.

2175782964 git-gui (Windows): use git-gui.exe in Create Desktop Shortcut
When calling `Repository>Create Desktop Shortcut`, Git GUI assumes
that it is okay to call `wish.exe` directly on Windows. However, in
Git for Windows 2.x' context, that leaves several crucial environment
variables uninitialized, resulting in a shortcut that does not work.

To fix those environment variable woes, Git for Windows comes with a
convenient `git-gui.exe`, so let's just use it when it is available.

7d5edeb7bc 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).

2846f75738 Win32: implement nanosecond-precision file times
We no longer use any of MSVCRT's stat-functions, so there's no need to
stick to a CRT-compatible 'struct stat' either.

Define and use our own POSIX-2013-compatible 'struct stat' with nanosecond-
precision file times.

Note: Due to performance issues when using git variants with different file
time resolutions, this patch does *not* yet enable nanosecond precision in
the Makefile (use 'make USE_NSEC=1').

bba92d880a 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.)

7708f31e07 mingw: ensure getcwd() reports the correct case
When switching the current working directory, say, in PowerShell, it is
quite possible to use a different capitalization than the one that is
recorded on disk. While doing the same in `cmd.exe` adjusts the
capitalization magically, that does not happen in PowerShell so that
`getcwd()` returns the current directory in a different way than is
recorded on disk.

Typically this creates no problems except when you call

	git log .

in a subdirectory called, say, "GIT/" but you switched to "Git/" and
your `getcwd()` reports the latter, then Git won't understand that you
wanted to see the history as per the `GIT/` subdirectory but it thinks you
wanted to see the history of some directory that may have existed in the
past (but actually never did).

So let's be extra careful to adjust the capitalization of the current
directory before working with it.

Reported by a few PowerShell power users ;-)

07e633bc97 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.

c1aa08f9ec prune: close directory earlier during loose-object directory traversal
27e1e22d (prune: factor out loose-object directory traversal, 2014-10-16)
introduced a new function for_each_loose_file_in_objdir() with a helper
for_each_file_in_obj_subdir(). The latter calls callbacks for each file
found during a directory traversal and finally also a callback for the
directory itself.

git-prune uses the function to clean up the object directory. In
particular, in the directory callback it calls rmdir(). On Windows XP,
this rmdir call fails, because the directory is still open while the
callback is called. Close the directory before calling the callback.

97b8effd40 winansi.c: Fix colourization on Cygwin pseudo terminals.
Git only colours the output and uses pagination if isatty() returns 1.
MSys and Cygwin emulate pseudo terminals via named pipes, meaning that
isatty() returns 0.

Commit 3adef8de55 fixed this for MSys
terminals, but not Cygwin.

The named pipes that Cygwin and Msys use are very similar.  MSys PTY pipes
are called 'msys-*-pty*' and Cygwin uses 'cygwin-*-pty*'.  This commit
modifies the existing check to allow both MSys and Cygwin PTY pipes to be
identified as TTYs.

Note that Pagination is still broken on Cygwin.  less.exe is spawned (as
seen in Process Explorer and using GIT_TRACE=1), but the output is not
being piped into it.
