flex bug with |'d patterns and $.

[Vern Paxson]

Greg Lee writes about flex mismatches regarding connecting multiple
rules with "|" when one of the rules includes the match-end-of-line
"$" meta-character.  This is indeed a bug and is documented as such
in the flex manual entry ("$" is an instance of trailing context).
I'm hoping to have all trailing context restrictions removed with
the next flex release.
