Almost: lbasename returns a pointer one character _after_ the last
slash. It also skips the drive letter on DOS/Windows (which might be
TRT, actually).
It would be reasonable to rewrite filename_dirrchr in terms of
lbasename, though, by backing up the pointer returned by lbasename if
it points to a slash, and otherwise returning NULL. The case of
"d:foo" should also be resolved (probably, return a pointer to the
colon).
