[GRASS5] [bug #1797] (grass) g.gisenv

[Harmisch Bowman via RT]

sorry about that last empty message, pressed enter in the wrong place.


With respect to being able to set a new mapset after the old has been set
incorrectly with g.gisenv, this seems to work fine, thanks. Can you forsee any
unwanted repercussions?

I'm still looking for a (gis lib) way of testing to see if a mapset/whatever
exists without the library function generating a fatal error. ?
(for test before G_setenv)
