Subject: [PATCH] MSYS2: Fixes for respecting trailing slashes during path
 conversion.

Allow '/' at end of path and prefixes in longest_ancestor_length

.. when new 'GIT_RUNNING_ANCESTOR_TEST' environment variable is set.

Unfortunately, there comes times that we run into semantic mismatches
between the Unix and the Windows worlds and this is one of those times.

This is a play to make more of the test-suite pass, but it is because
some of the assumptions about '/' don't hold true on Windows.

For a start, there isn't really a '/' on Windows since it doesn't obey
FHS; rather there's a bunch of drive letters. Instead Cygwin implements
a POSIX layer that obeys FHS above all of those drive letters and MSYS2
takes all of that good stuff and adds a few of its own bits and pieces:

When MSYS2 calls native Windows software it converts things that look
like Unix paths to Windows paths, so when it sees '/' it converts it
to whereever MSYS2 was intalled (actually based on where msys-2.0.dll
is located). One of the rules of this path conversion is to respect
the existence or not of any trailing '/', so if there was one at the
end of the Unix path then there'll still be one at the end of the
Windows version. This also applies to the root, '/', a decision which
simplifies things (i.e. fixes bugs) a lot and is eminently sensible
(i.e. it makes simple path concatenation just work without needing to
check whether we need to insert an '/' in-between).

By applying the hack when _WIN32 is defined and GIT_RUNNING_ANCESTOR_TEST
is set, the chances of distrubing other things should be minimized.

Also, in t/t0060-path-utils.sh, rootoff must be adjusted by an extra 1
due to '/' retaining it's trailing '/' post-conversion.
