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.
