YACC complains about ambiguities, though it will still cope with them.
The Lojban grammar reports zero conflicts, so it is unambiguous,
EXCEPT for the various hacks put in to keep YACC from spotting places
where 1-token lookahead isn't enough. Ambiguities can lurk there, and
have to be searched for by hand.
