Comment (by glynn):

 Replying to [ticket:1051 msieczka]:
 > The mapset search path in mapset2 is wrong:
 $ g.gisenv get=MAPSET

 g.mapsets -p
 mapset1 PERMANENT mapset2
 > If maps of the same names exist in mapset1 and mapset2, GRASS will pick
 the one from mapset1 although the current mapset is mapset2. This might
 lead to various troubles.

 This isn't necessarily a problem. GRASS itself doesn't care whether the
 current mapset is first in the search path, or even if it's in the search
 path at all.

 OTOH, it's probably a good idea for the GUI interface to place additional
 mapsets after the current mapset, at least by default.

 However: I'd like to take this opportunity to remind programmers that an
 unqualified input map name does '''NOT''' necessarily refer to the map of
 that name in the '''current''' mapset, but to the first map with that name
 found in the mapset search path (which may '''or may not''' have the
 current mapset first).

 If you intend to refer specifically to a map in the current mapset, you
 '''need''' to specify the mapset.
