I don't see that as such a problem.  Maybe it should just exit an do
nothing in that case.  With OP's mention of vectors, I assumed an older
version of d.vect was being used where there once were bugs regarding
setting the drawing command list so d.zoom wouldn't know about previous
d.vect commands...
