Issue mentioned in user ML by Hamish.

Design decision needed - should breaks be used for both horizontal and
vertical breaks or it should be renamed to h_breaks and v_breaks?

Original message:
20deg reprojected grid lines are a bit ugly, apparently we
need to extend the v.mkgrid breaks= option to work on vertical
lines as well as the horizontal ones.

Thanks...

I added breaks to vertical lines to v.mkgrid, please check the attached
patch.

In the screenshots you can see:
  * red lines: old behavior of v.mkgrid
  * blue lines: new behavior of v.mkgrid with default breaks value (3)
  * green lines: new behavior of v.mkgrid with breaks value 30
