For a pathspec like 'foo/bar' comparing against a path named "foo/",
namelen will be 4, and match[namelen] will be 'b'. The correct location
of the directory separator is namelen-1.
The reason the code worked anyway was that the following code immediately
checked whether the first matchlen characters matched (which they do) and
then bailed and return MATCHED_RECURSIVELY anyway since wildmatch doesn't
have the ability to check if "name" can be matched as a directory (or
prefix) against the pathspec.
