grep: stop using PARSE_OPT_NO_INTERNAL_HELP

Browse source 
The flag PARSE_OPT_NO_INTERNAL_HELP is set to allow overriding the
option -h, except when it's the only one given.  This is the default
behavior now, so remove the flag and the hand-rolled --help-all
handling.  The internal --help-all handler now actually shows hidden
options, i.e. --debug in this case.
