Comment (by mmetz):
Replying to [ticket:2718 neteler]:
> When creating a grid and the map extent does not reach more than half of
a row size, the resulting grid is one row too small (see screenshot).
The reason is that enlarging the region can be dangerous, e.g. beyond 90N
/ 90S in latlong. Therefore it is saver to skip one row in the grid if
that grid row would extend beyond the current regions bounds.
When setting the current region from a vector, extents and resolution
should be adjusted afterwards in order to fit your needs.
>
> Solution: add a flag to enforce full coverage using a different rounding
method.
or set your current region accordingly, before running v.mkgrid.
