I have tried to fix this, but I don't know the code. The previous logic was
obviously (?) broken, as it had this (paraphrased):

if (remove_directories || matches)
	remove_dir_recursively(...);

which should have been &&. But with only this change, top-level directories
were not removed even if "-d" was given. Looking at the (!ISDIR) branch, I
guessed that it should instead trigger if pathspec is NULL; i.e, generally
treat (!pathspec) as a match. It looks like the behaviour is correct now, but
somebody who knows this code should check my guesses.

-j.
