[GRASS-dev] where= and cats= to all vector commands

[Wolf Bergenheim]

Hi developers,

What do you people think of the idea to add where= and cats= parameters
to all vector commands? Also add any missing layer= parameter (like with
v.voronoi).

What should be the case where both cats and where is supplied? Ideally
merging it so that first do the where, and then limit the result to only
cats in the given list? Or output a warning that where takes precedence
over cats?
