[GRASS-dev] Plan to build Package to use GRASS from R

note that --overwrite comes and goes depending of if it is relevant
to the module.

re. the module list of flag from r.buffer --help: the vertical descriptions
of flags uses the short version (--q), but note that the top USAGE: line
has the long version. Both ways are listed there on purpose as a hint.
