Michael Eischer bcc3bddcf4 filter: only check whether a child path could match when necessary ...

When checking excludes there is no need to test whether a child path
could also match the pattern, as it is by definition excluded.
Previously childMayMatch was calculated but then discarded. For simple
absolute paths this can account for half the time spent for checking
pattern matches.
