Exactly the same comment applies here. If we are using pathspec, we
should already have a loop that calls ce_path_match() for each and
every path we know about, and we should be updating the code to
collect "have we used all pathspec elements?" information at the
same time if it is not doing so already. Let's not make another
loop that checks what we should already be doing elsewhere.
Thanks.
