Hello,

In your description you say "Though Windows may use /, , or \ as path separators, you can only use forward-slashes (/) when specifying glob expressions. Any back-slashes () will be interpreted as escape characters instead of path separators."

Tests I ran suggest it should be the opposite. I am using Windows 7.

I wanted to list all files except some, so I used forward slashes as per your suggestion '!(**.jpg|css/style.css)'
This kept throwing an error and failing. When I modified it to use back-slashes instead '!(**.jpg|css\\style.css)' it worked flawlessly.
