[GRASS-dev] correction r.mapcalc help file

[Paulo van Breugel]

Dear devs,

In the help file of r.mapcalc it is written:

> When the user enters input to /r.mapcalc/ non-interactively on the 
> command line, the program will not warn the user not to overwrite 
> existing map layers. Users should therefore take care to assign 
> program outputs raster map names that do not yet exist in their 
> current mapsets. 

Perhaps the description is somewhat ambiguous, but if the way I read 
this is correct, this is not the default behaviour. Perhaps the 
following describes it better:

> By default it is not possible to overwrite existing raster layers, so 
> the user is expected to take care to assign program output raster 
> names that do not yet exist in their current mapset. If they want to 
> overwrite existing maps, users can use the --overwrite flag.

I added a patch file in case the above is ok.

Best wishes,

Paulo
