[PATCH 4/8] dir: exit before wildcard fall-through if there is no wildcard

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

The DO_MATCH_LEADING_PATHSPEC had a fall-through case for if there was a
wildcard, noting that we don't yet have enough information to determine
if a further paths under the current directory might match due to the
presence of wildcards.  But if we have no wildcards in our pathspec,
then we shouldn't get to that fall-through case.
