[docs] [issue8402] Add a way to escape metacharacters in glob/fnmatch

This is a backward incompatible change. For example glob.glob(r'C:\Program Files\*') will be broken.

As flacs says a way to escape metacharacters in glob/fnmatch already exists. If someone want to match literal name "Ajax_[version2].txt" it should use pattern "Ajax_[[]version2].txt". Documentation should explicitly mentions such way.

It will be good also to add new fnmatch.escape() function.
