An event record never carries flag 2, as no expansion record follows; flag 1 reads the first word

In acme flag 2 promises a second record with the expanded range, and
acme's libraries read one. F records set it always and a click with no
range known set it, with none following: a library then took the next
event for it. Records here carry the word already, so 2 is never set.
Flag 1 now reads the first word as acme's lookup does, so `Msg hi` is 1.
