I think normal regexps aren't the right tool for this, you can do it
easily in a couple of lines of C, but that method would be somewhat slow
in perl.  But given that you're dealing with IMAP, the network is going
to be a lot slower, so you might as well just do it with a for loop over
the characters and count parentheses, rather than some totally obscure
regexp hack.
