Or even better, use common_prefix()'s return value here. I took me a
while to realize this code was not buggy. It is fine to just pick the
first item because the first <len> characters of _all_ pathspec items
must be the same. Something like this

prefix = common_prefix(..)
read_directory(..., prefix, strlen(prefix), pathspec);

expresses it much better. Yeah one extra mem allocation, no big deal
since fill_directory() is not called very often.
