This is uncorrect. It works fine but you have to be in the correct
directory.


e.g. these all work:

cd $MAPSET
grass61 `pwd`

# this works but mapset name in g.gisenv is ".", which is bad
cd $MAPSET
grass61 .

cd $LOCATION
grass61 $MAPSET

cd $GISDBASE
grass61 $LOCATION/$MAPSET

and finally
grass61 $GISDBASE/$LOCATION/$MAPSET


the trick is you have to be in the correct part of the file system.
e.g. if $MAPSET = $USER, grass61 $USER from /home could very well be
ambiguous.


This seems like a good time to again call for an enhancement to the
TclTk startup screen: double clicking on a mapset name should imply
"continue".
