[GRASS5] $LOCATION or not $LOCATION ?

[Markus Neteler]

Hi

for some time the $LOCATION variable is gone now and must
be constructed with 'g.gisenv'. As far as I know the underlying
idea was to allow for GRASS parallel sessions.

Since that feature is not (yet) functional, should we re-enable
the $LOCATION (e.g. in ETC/Init.sh) until GRASS parallel sessions
become possible? $LOCATION is pretty often used and quite
convenient over constructing (more or less) on the fly with g.gisenv.
