grass.gisenv() will run g.gisenv for each call.

It would be better to save the result, i.e.:

	env = grass.gisenv()
	...
	... = env['MAPSET']

But in wxGUI, you might want a more sophisticated interface, which
allows environment changes. E.g. returning the environment as a
UserDict object which runs "g.gisenv set=..." whenever it's updated
(os.environ is implemented similarly; it calls putenv() whenever an
entry is updated).

Or maybe it would be better to just write out the internal environment
to a temporary $GISRC file for each command.
