Description
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. http://lists.osgeo.org/pipermail/grass-user/2012-July/065214.html

Anyone able to extend the breaks to vertical lines in v.mkgrid? 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
