Linus:
get_pathspec() does turn '.' into an empty string (which is
correct - git internally does _not_ ever understand the notion of
"." as the current working directory), but it doesn't ever do the
optimization of noticing that a pathspec that consists solely of
an empty string is "equivalent" to an empty pathspec.
The test is to ensure that this behaviour stays.
