* New option -q, --quiet, rcfile option "quiet" implemented.  Skips printing
          errors about the rcfile and asking user to press enter.  Also, nano should
          now only ask for one enter press when there is an error when not using -q.
          Based on discussion between Eitan Adler and Mike Frysinger.
        * rcfile.c (parse_keybinding) -  Significant cleanups and fixes for
          detecting and reporting errors in key bindings code.
