Vectors will ignore region except conversion into raster. I think that all vector
modules ignore region now.

As I wrote in mail "new vector2" I propose move bounding box from dig
into dig_plus.

I think always merge modules if possible.

I want merge into v.category in g51 (and add: delete category, change
category number, ...)
(always merge modules if possible)

Cutting areas is not so simple and we have already v.cutter.
I think that additional option for v.cutter
-r    use current region insted of cutter map
should help.
