 The need this patch scratches is real, but I have not yet been able to
 dedicate the time to properly consider if it is the right approach to
 solve it. see my original comment to this wish -- we can make the units
 automatic like the Tcl profile tool and NVIZ's scalebar; obviously 0 to
 60000m should be converted to km. I think the Tcl and NVIZ threshold rules
 are pretty good and we could use them; or perhaps d.barscale's heuristic
 rules. Only issue with that is if user wants miles not km (like
 'd.barscale -f').

 I don't like to bother users with lots of complicated controls for things
 which it is reasonable for the software to do for them.

 another semi-related idea is to add an option to take legend units from
 the raster map's 'r.support units=' setting.

 Sorry for the delay in dealing with this, my available time these days is
 rather limited.
