I'm not sure for GRASS, but I think that in both cases the limits will 
be mostly defined by your OS (i.e. max number of sub-directories or max 
number of files), and not by the program.

You can try it out in a test location, loopping through g.mapset -c 
commands to see whether you reach a limit at one point.
