Hmm, do we want to break and return path_handled here, to cause
the calling read_directory_recursive() to call dir_add_name()?

Also I suspect that (dir->flags & DIR_COLLECT_IGNORED) needs to be checked
before making this call.

We would probably call a structure of this shape "dir_array", as I haven't
seen us calling anything "vector" for naming consistency.

Instead of introducing two dir-arrays for different kinds of ignoredness,
it may be cleaner to add one bit (or more for later expansion) to dir_entry
and mark the ones in ignored dir-array with the ignore reason.
