Patch from Konstantin Isakov <ikm@pisem.net>:
In most cases, dirname returns the same argument it was given, so this code
works nice, but there's one special case: when the name contains no
dirname, it returns "." (stored statically in the body of itself), and we
get a segfault in attempt to free() it.
This patch fixes this problem.
