[PATCH] Fix a small memory leak in builtin-add

[Benoit Sigoure <tsuna@lrde.epita.fr>]

prune_directory and fill_directory allocated one byte per pathspec and never
freed it.

I don't know whether this was intentionnal or not (since it's only a matter of
having small chunks of memory not being reclaimed and I don't think we can
enter these functions twice, so these are not leaks in the sense that the
program will consume more and more memory).  But if it was intentionnal,
wouldn't it be better to put a small comment in the code saying so (so that
casual readers like me won't get surprised).
