This is not seen by rgrass::parseGRASS(), but a section could be added to 
list bin/*.bat files in the GRASS_ADDON_BASE environment variable 
directory. Do users also install addons system-wide (there is an option in 
the GUI)? Where does install if the -s flag is given - do we need to look 
there too?

What happens to C/C++ Windows extensions, are they in the GRASS_ADDON_BASE 
\bin with an .exe extension?

Contributions welcome!
