gnubol: COBOL Grammar Nucleus Level 2 with error productions

[Tim Josling <TIMJOSLING@prodigy.net>]

I've added error productions to the grammar at timjosling.homepage.com. Basically
I am rcovering at full stops, and prior to the next verb.

This means that

IF error
   display
ELSE
   display
END-IF

Will produce errors at the ELSE and END-IF. I haven't been able to produce error
productions that don't produce zillions on grammar conflicts to deal with these
situations.

The good news if that the nest statements do get checked.

I will be quiet for a while while I try and get hacks #1 - #13 working. ciao
