Having a warning for a "shadow" is a good idea; an error isn't.

You can't; at least not with g.rename. You will have to manually
rename the corresponding files/directories with "mv". 

G_legal_filename() should be changed to prohibit commas in map names. 
Probably some other characters (e.g. '@') as well.

Currently, it allows any byte between 33 and 126 inclusive except for
slash, double-quote and single-quote.

Some of those will conflict with GRASS syntax (e.g. comma, at,
equals), while others aren't legal in Windows filenames (e.g. 
backslash, query, asterisk).
