cb6c565eab Additional memory initialization in lemon - bug reported from wireshark.
Ticket #2172.  Note this problem only comes up with certain grammars,
and does not impact SQLite.  On the other hand, it might cause SQLite
to run slower.  So we might want to revisit this change at some point. (CVS 3594)
