If PGE supported character classes in globs right now, we'd probably
pass another 50 or 60 tests from the Tcl suite without writing any
more code for the interpreter.
Oh. It's hard to resist a win like that, so...
Character classes in globs are now supported in r8529. :-)
I also adjusted PGE's subrule name searching semantics a bit so that
<lower> works as we would expect.
