As Graham says, there's no need to reopen #1240; it works fine, even
if it slows things down a bit.  Hopefully Joe can come up with some
more optimizing to reduce its impact.

Ha, I just commented those bits out. :)  The main issue was converting
prefix \cresc to postfix notation, so there are still plenty of things
which need sorting out (quite a few overflowing pages, it seems).

I'll send you a patch once I've tidied it up a bit.

No problem; I've been letting it run overnight, so it's not costing
much time to benchmark.

I'm half hoping my computer will give up the ghost soon so I can
justify upgrading to something a bit nippier (MOAR CORES!)
