See Hamish's reply.

AFAICT, the problem with g.gisenv is that it checks for argc==1 before
calling G_parser(), so e.g. "g.gisenv --quiet" causes that check to
fail.

What it should probably do is to call G_parser() unconditionally, then
check for:

	if (!get->answer && !set->answer && !store_opt->answer)

I suspect that this is unnecessary if the no-arguments check is fixed.
