cherry-pick will segfault when transplanting a root commit if the --ff
option is used. This happens because the "parent" pointer is set to NULL
when the commit being cherry-picked has no parents. Later, when "parent"
is dereferenced, the cherry-pick segfaults.
Fix this by checking whether "parent" is NULL before dereferencing it and
add a test for this case of cherry-picking a root commit with --ff.

As of 2dbc887e, shell.c employs execv(), so provide a MinGW-specific
mingw_execv() override, complementing existing mingw_execvp() and
cousins.
As a bonus, this also resolves a compilation warning due to an
execv() prototype mismatch between Linux and MinGW. Linux expects
the second argument to be (char *const *), whereas MinGW expects
(const char *const *).

On Windows, we would like to be able to have a default http.sslCAinfo
that points to an MSys path (i.e. relative to the installation root of
Git). As Git is a MinGW program, it has to handle the conversion
of the MSys path into a MinGW32 path itself.
Since system_path() considers paths starting with '/' as absolute, we
have to convince it to make a Windows path by stripping the leading
slash.

Currently git-stash uses `git rev-parse --no-revs -- "$@"` to set its
FLAGS variable. This is the same as `FLAGS="-- $@"`. It should use
`git rev-parse --no-revs --flags "$@"`, but that eats any "-q" or
"--quiet" argument. So move the check for quiet before rev-parse.

Recently, the 'stash show' functionality was broken for the case when a
stash-like argument was supplied. Since, commit 9bf09e, 'stash show' when
supplied a stash-like argument prints nothing and still exists with a zero

since the output of 'stash show' was not verified to be correct.
Improve and expand on the existing tests so that this flaws is detected.

When we're diffing symlinks, we consider the contents to be
the pathname that the symlink points to. When a user sets up
a userdiff driver like "*.pdf diff=pdf", their "diff.pdf.*"
config generally tells us what to do with the content of
pdf files.
With the current code, we will actually process a symlink
like "link.pdf" using a configured pdf driver, meaning we
are using contents which consist of a pathname with
configuration that is expecting contents that consist of an
actual pdf file.
The most noticeable example of this would have been
textconv; however, it was already protected in its own
textconv-specific code path. We can still see the breakage
with something like "diff.*.binary", though. You could
also see it with diff.*.funcname, though it is a bit harder
to trigger accidentally there.
This patch adds a check for S_ISREG lower in the callstack
than the textconv-specific check, which should block use of
any userdiff config for non-regular files. We can drop the
check in the textconv code, which is now redundant.

By default, MSYS sed throws away CR from CRLF line-endings. Tests
t6038.5 and t6038.6 employ sed to normalize conflict output of git-merge
for validation purposes. These tests expect CRLF line-endings to be
present in the normalized output of git-merge, and thus fail when sed
undesirably removes CR. Fix by employing sed's -b/--binary switch to
suppress its default behavior of dropping CR characters.

Upon program invocation, MSYS converts environment variables containing
path-like values from Unix-style to DOS-style under the assumption that
the program being invoked understands only DOS-style pathnames. For
instance, the Unix-style path /msysgit is translated to c:/msysgit. For
test t5560, the path being requested from git-http-backend is specified
via environment variable PATH_INFO as a URL path of the form
/repo.git/foobar, which git-http-backend combines with GIT_PROJECT_ROOT
to determine the actual physical path within the repository. This is a
case where MSYS's conversion of the path-like value of PATH_INFO causes
harm, for two reasons. First, the resulting converted path, when joined
with GIT_PROJECT_ROOT is bogus (for instance,
"C:/msysgit/git/t/trash-zzz/C:/msysgit/repo.git/HEAD"). Second, the
converted PATH_INFO path is rejected by git-http-backend as an 'alias'
due to validation failure on the part of daemon_avoid_alias().
Unfortunately, the standard work-around of doubling the leading slash
(i.e. //repo.git/foobar) to suppress MSYS path conversion works only for
command-line arguments, but not for environment variables.
Consequently, side step the problem by instead passing git-http-backend
an already-constructed full path rather than components GIT_PROJECT_ROOT
and PATH_INFO.
