d.zoom should use the commands: list.

Trying to segregate everything into raster/vector simply doesn't work. 
d.rgb fails similarly, and there are almost certainly other cases. 

Also, all vector maps are redrawn with "d.vect map=<name>", ignoring
the 25 options and 3 flags which may have been used when originally
drawing the map. At least d.rast only has 3 options and 2 flags (which
are similarly ignored).
