Every time I try to use lex's start states something breaks. This
time, it recognized something in a state that was not active. I
did not track this one down because of sheer disgust: I just
switched to flex. I've already discovered what is either an
incompatibility in flex or a bug, but at least I can fix that!

In the Sys V3.2 manual on lex, they no longer document start states.
I guess they couldn't make them work either.  Keep in mind that lex
was written as an undergraduate summer intern's project at Bell Labs.

Good thinking.

There's a lot else wrong with that manual, including the claim that lex
terminates on an input function return of EOF when it actually requires a 0.

I have made higher-ups at AT&T aware that the manual is bogus, and been
promised that the Lesk paper and a lot of the other technical docs that had
fallen by the wayside will be restored to the documentation set.
