Is : really a problem, given that the name in question will be appended
to a known directory's path?

I'm not convinced that . is issue-free.  On most if not all versions of Unix,
you are allowed to open a directory as a file and read the filenames it
contains.  While I don't say it'd be easy to manage that through
tsearch, there's at least a potential for discovering the filenames
present in . and .. --- how much do we care about that?
