By default wildmatch(,, 0) is equivalent with fnmatch(,, FNM_PATHNAME).
This patch makes wildmatch behave more like fnmatch: FNM_PATHNAME
behavior is always applied when FNM_PATHNAME is passed to
wildmatch. Without FNM_PATHNAME, wildmatch accepts '/' in '?' and '[]'
and treats '*' like '**' in the original version.

The choice of name "pathspec" is not good. I couldn't think of
anything appropriate and just did not care enough at this point.
