If G__getenv("MONITOR") returned NULL it caused problems for G_store. But 
it seems you don't need to use G_store anyway as the values returned by 
G__getenv are stored in some kind of static memory structure.

I committed some fixes (well I hope they are fixes) to g.mapset which 
seems to fix this and tidy up some other string handling. And it looked 
like it printed a message to the screen saying it was cleaning the temp 
directory but didn't actually do that---I changed that too.

Please test- I hope I didn't break anything.
