No idea. The ecpg grammar in the main tree has about 530 rules, while my
actual version is at nearly 550. The main grammar should be at about
440. So there's some room left.

Actually I already ate the really low-hanging fruit. :-)

I did spend some time to reduce the states, albeit surely not to the
extent possible, but still it will mean quite some work I'm afraid.
