There is no need to have GISBASE variable set (path to directory where
GRASS binaries live) when GRASS GIS is started explicitly as a 'grass'
command later on. If you have GISBASE, grass command will end with error as
GISBASE says that you are already in GRASS session.

Why GISBASE is set, or if deleting it is just a precaution, I have no idea.

Best,
Vaclav

but this commit should fix it
