I don't think it should have a default value -- all calls to this module
should be explicit. Valuable maps are kept in PERMANENT and it could be
dangerous to dump users in there by default. Similar argument to not
running user code as root. If you use the same mapset names in different
locations then this isn't a problem? (e.g. MAPSET=$USER)

While "no known bugs", I don't think using this module to switch
locations (or gisdbase) should be encouraged for everyday use. It's
better to restart GRASS. i.e. Init.sh checks, cleanup, command history,
etc, should all be used if possible -- reserve g.mapset for changing
mapsets and for scripting.
