Hello, 

a flag for each module to delete a raster/vector if the file already exists 
would be good.
A hidden g.remove with the respective name would do the job. That would make 
it easier for users to play with certain settings and not substituting each 
time the old name or run g.remove. 

BTW the delete file handling is not consistent (but I think that has been 
discussed earlier) r.mapcalc is just overwriting the file but e.g. r.rescale 
does prompt an error message that the file exist.

regards, Martin
