edbc400b6f t5580: test cloning without file://, test fetching via UNC paths
It gets a bit silly to add the commands to the name of the test script,
so let's just rename it while we're testing more UNC stuff.

20027f8b02 mingw: special-case arguments to sh
The MSYS2 runtime does its best to emulate the command-line wildcard
expansion and de-quoting which would be performed by the calling Unix
shell on Unix systems.

Those Unix shell quoting rules differ from the quoting rules applying to
Windows' cmd and Powershell, making it a little awkward to quote
command-line parameters properly when spawning other processes.

In particular, git.exe passes arguments to subprocesses that are *not*
intended to be interpreted as wildcards, and if they contain
backslashes, those are not to be interpreted as escape characters, e.g.
when passing Windows paths.

Note: this is only a problem when calling MSYS2 executables, not when
calling MINGW executables such as git.exe. However, we do call MSYS2
executables frequently, most notably when setting the use_shell flag in
the child_process structure.

There is no elegant way to determine whether the .exe file to be
executed is an MSYS2 program or a MINGW one. But since the use case of
passing a command line through the shell is so prevalent, we need to
work around this issue at least when executing sh.exe.

Let's introduce an ugly, hard-coded test whether argv[0] is "sh", and
whether it refers to the MSYS2 Bash, to determine whether we need to
quote the arguments differently than usual.

That still does not fix the issue completely, but at least it is
something.

Incidentally, this also fixes the problem where `git clone \\server\repo`
failed due to incorrect handling of the backslashes when handing the path
to the git-upload-pack process.

133fee9581 mingw (t5580): document bug when cloning from backslashed UNC paths
Due to a quirk in Git's method to spawn git-upload-pack, there is a
problem when passing paths with backslashes in them: Git will force the
command-line through the shell, which has different quoting semantics in
Git for Windows (being an MSYS2 program) than regular Win32 executables
such as git.exe itself.

The symptom is that the first of the two backslashes in UNC paths of the
form \\myserver\folder\repository.git is *stripped off*.

Document this bug by introducing a test case.

873d1cd65d mingw: demonstrate a problem with certain absolute paths
On Windows, there are several categories of absolute paths. One such
category starts with a backslash and is implicitly relative to the
drive associated with the current working directory. Example:

	c:
	git clone https://github.com/git-for-windows/git \G4W

should clone into C:\G4W.

There is currently a problem with that, in that mingw_mktemp() does not
expect the _wmktemp() function to prefix the absolute path with the
drive prefix, and as a consequence, the resulting path does not fit into
the originally-passed string buffer. The symptom is a "Result too large"
error.

86f4b95fcc t9001: work around hard-to-debug hangs
Just like the workaround we added for t9116, t9001.83 hangs sometimes --
but not always! -- when being run in the Git for Windows SDK.

The issue seems to be related to redirection via a pipe, but it is really
hard to diagnose, what with git.exe (a non-MSYS2 program) calling a Perl
script (which is executed by an MSYS2 Perl), piping into another MSYS2
program.

As hunting time is scarce these days, simply work around this for now and
leave the real diagnosis and resolution for later.

c1ce85eb3e rebase -i: rearrange fixup/squash lines using the rebase--helper
This operation has quadratic complexity, which is especially painful
on Windows, where shell scripts are *already* slow (mainly due to the
overhead of the POSIX emulation layer).

Let's reimplement this with linear complexity (using a hash map to
match the commits' subject lines) for the common case; Sadly, the
fixup/squash feature's design neglected performance considerations,
allowing arbitrary prefixes (read: `fixup! hell` will match the
commit subject `hello world`), which means that we are stuck with
quadratic performance in the worst case.

The reimplemented logic also happens to fix a bug where commented-out
lines (representing empty patches) were dropped by the previous code.

While at it, clarify how the fixup/squash feature works in `git rebase
-i`'s man page.

3b3c32d54e Unbreak interactive GPG prompt upon signing
With the recent update in efee955 (gpg-interface: check gpg signature
creation status, 2016-06-17), we ask GPG to send all status updates to
stderr, and then catch the stderr in an strbuf.

But GPG might fail, and send error messages to stderr. And we simply
do not show them to the user.

Even worse: this swallows any interactive prompt for a passphrase. And
detaches stderr from the tty so that the passphrase cannot be read.

So while the first problem could be fixed (by printing the captured
stderr upon error), the second problem cannot be easily fixed, and
presents a major regression.

So let's just revert commit efee9553a4.

ad43224c99 reset: support the experimental --stdin option
Just like with other Git commands, this option makes it read the paths
from the standard input. It comes in handy when resetting many, many
paths at once and wildcards are not an option (e.g. when the paths are
generated by a tool).

Note: we first parse the entire list and perform the actual reset action
only in a second phase. Not only does this make things simpler, it also
helps performance, as do_diff_cache() traverses the index and the
(sorted) pathspecs in simultaneously to avoid unnecessary lookups.

This feature is marked experimental because it is still under review in
the upstream Git project.

when changing the original patch that marked the .git/ directory as

327460ff46 status: offer *not* to lock the index and update it
When a third-party tool periodically runs `git status` in order to keep
track of the state of the working tree, it is a bad idea to lock the
index: it might interfere with interactive commands executed by the
user, e.g. when the user wants to commit files.

Let's introduce the option `--no-lock-index` to prevent such problems.
The idea is that the third-party tool calls `git status` with this
option, preventing it from ever updating the index.

The downside is that the periodic `git status` calls will be a little
bit more wasteful because they may have to refresh the index repeatedly,
only to throw away the updates when it exits. This cannot really be
helped, though, as tools wanting to get a periodic update of the status
have no way to predict when the user may want to lock the index herself.

Note that the regression test added in this commit does not *really*
verify that no index.lock file was written; that test is not possible in
a portable way. Instead, we verify that .git/index is rewritten *only*
when `git status` is run without `--no-lock-index`.

43b4dd8918 git bundle create <bundle> leaks handle the revlist is empty.
issue #790: git bundle create does not close handle to *.lock file

This problem happens when an user tries to create an empty bundle, using the
following command:  `git bundle create <bundle> <revlist>` and when <revlist>
resolve to an empty list (for example, like `master..master`), `git bundle` fails
and warn the user about how it don't want to create empty bundle.

In that case, git tries to delete the `<bundle>.lock` file, and since there's still
an open file handle, fails to do so and ask the user if it should retry (which will
fail again).

The lock can still be deleted manually by the user (and it is required if the user
want to create a bundle after revising his rev-list).
