BUG: Move previous parser bugfixes into input file

The command argument parser code is generated by bison.  This change
restores some fixes previously applied to the generated output that were
destroyed by regenerating the parser source.  This time the fixes have
been put in the input file so regenerating the parser will not destroy
them again.
