The point is that *any* options (even ones which have no effect, e.g.
--quiet or --verbose) caused the argc==1 check to fail.

I've now changed it so that if you specify neither get= nor set=, it
will print the current settings.

Apart from not being confused by --quiet etc, you should now be able
to use "g.gisenv store=mapset" to list the VAR file.
