Nguyễn Thái Ngọc Duy e5bbe09e88 wildmatch: change behavior of "foo**bar" in WM_PATHNAME mode
In WM_PATHNAME mode (or FNM_PATHNAME), '*' does not match '/' and '**'
can but only in three patterns:

- '**/' matches zero or more leading directories
- '/**/' matches zero or more directories in between
- '/**' matches zero or more trailing directories/files

When '**' is present but not in one of these patterns, the current
behavior is consider the pattern invalid and stop matching. In other
words, 'foo**bar' never matches anything, whatever you throw at it.

This behavior is arguably a bit confusing partly because we can't
really tell the user their pattern is invalid so that they can fix
it. So instead, tolerate it and make '**' act like two regular '*'s
(which is essentially the same as a single asterisk). This behavior
seems more predictable.
