Summary:  support EOF as a terminal

Original Submission:  It would be nice to recognize end-of-file as a terminal;

It shouldn't be hard to implement.

Should we recognize it as a token only if requested via an option? I think not, 
it's easy to give it an 'ignore' action, and if the user forgets it he/she will 
get an exception at the first run of the scanner.

Ocamllex has it, and epsilonlex should have it too.
