The problem's not the parsing, it's the fact that you don't have
appropriate chunks corresponding to directories for the scanner to loop
over once pattern matching has parsed it.

The only way I can see is effectively to parse it first in the globbing
code to treat a complete set of parentheses specially.  But this is
going to be inconsistent with pattern matching one way or another.  So a
different syntax would be more sensible.

I think Bart's answered this.
