Comment:

 I think the size should be specified in map units, for example user can
 say `size=250` to get 250m scale bar. This seems like a simple and
 actually a desired option. What are the units there probably depend on the
 rest of the implementation or interface of d.barscale. With the current
 implementation it would be probably meters by default but it should be
 feet when the `-f` is used.
