@nedbat I wonder if this has the same problem with the prefix..

(r"/\*\*+$", r"[/\\\\].*"), # /**$ matches any slash-suffix.

@nedbat at first I thought I'd just send a test case demonstrating the problem, but then, I thought it should be easy to fix, so I've added this change as well. I don't know if there was a motivation for things to work as they do, but hopefully this can improve the behavior and match it with what's documented…

(r"\*\*/", r"(.*[/\\\\])?"), # **/ matches any subdirs, including none
(r"/", r"[/\\\\]"), # / matches either slash or backslash
(r"\*", r"[^/\\\\]*"), # * matches any number of non slash-likes
