Subject: [PATCH] since we're always running info_cmp in the end, remove the
 whole "in case of emergency run info_cmp block" (more efficient: we only
 parse the entry we need). Keep the small part that creates a dumb terminal on
 VMS, even though we're not running that.

Add an extra state check in the automaton to avoid skipping a tmp_term
