Subject: [PATCH] Don't fall back to pwd for Git dir of blank filename

In particular, this fixes `FugitiveFind(..., '')` to respect the empty
Git dir argument rather than falling back to detection on the current
working directory.  Which in turn fixes :Gstatus using the current
working directory when called from a buffer that does not belong to a
repository.
