Ok, so this is how PARSEOPT_OPTS gets used.  It is a way for the
command that sources git-sh-setup to tell the parseopt code what
to do.  I can agree with this, but then all the other commands
that do not set PARSEOPT_OPTS before sourcing git-sh-setup
should set it to empty string.  Otherwise the users can screw
you with their environment variables.
