Yeah, I was wondering about that. I wouldn't do it exactly like
that, but with a check that the entry gets matched somewhere.
The other patchset adds cross-checks that each ecpg.addons entry is
used exactly once, but there's no such check for these arrays that
are internal to parse.pl. Can't quite decide if it's worth adding.

I debugged the patch in this thread by checking that the emitted
preproc.y didn't change, but that might not be helpful for changes
that are actually intended to change the grammar.
