I think that the function 'unmsys--file-name' is conceptually wrong, because:

1. It assumes that every MSYS path will match the "/c/foo/bar"
pattern, which in general is false (as we've already seen).

2. Some directory "c:/whatever" could be mounted in MSYS as "/c/foo",
and therefore "/c/foo/bar" should be translated as "c:/whatever/bar"
(not "c:/foo/bar"). Improbable but possible.

Therefore, like I've said before, IMO this is unreliable, and we
should translate (or "unmsys") _all_ MSYS paths with the 'msys-to-w32'
script.
