 `classic` and `line` styles in ''d.barscale'' have capital N with a simple
 arrow over it. This should be optional (set by a flag), ideally for every
 style.

 The issue I can see is that when we make it optional and you used
 `style=classic` and `style=line` in you script, then you won't get north
 arrow anymore. So, just introducing flag to include the north arrow is in
 fact API break. The solution would be adding another flag which would turn
 it off for these two. I'm not sure if it is worth it but it might be
 important to somebody.
