fnmatch patterns are not BRe's (for example '.' is not special
to fnmatch expressions, and '?' is missing from above); but the first 3
characters have no special meaning, that's common to both.

If that was the case, there would be no way to quote something inside
a bracket expression, so you could never have a '/' or ']' in a bracket
expression. I think that is a defect. Here's is a case where complying
to an ambiguous standard, makes functionality worse, and I would file
a defect with ToG.
