dir.c: literal match with wildcard in pathspec should still glob

When a path with wildcard characters, e.g. 'f*o', exists in the
working tree, "git add -- 'f*o'" stops after happily finding
that there is 'f*o' and adding it to the index, without
realizing there may be other paths, e.g. 'foooo', that may match
the given pathspec.

This is because dir.c:do_match_pathspec() disables further
matches with pathspec when it finds an exact match.
