rHGcf15c3cc304c: match: make base matcher return True for visitdir
Summary

If a matcher doesn't implement visitdir, we should be returning True so that
tree traversals are not prematurely pruned. The old value of False would prevent
tree traversals when using any matcher that didn't implement visitdir.
