I agree that it would be helpful to have an opion in v.category to copy
the values from one layer to another (i.e. something like option=copy
layer=2 sourcelayer=1).

I just filed an enhancement request with a proposed patch implementing this (http://trac.osgeo.org/grass/ticket/1498). The proposed implementation works as follows:

v.category roadsmajor option=transfer layer=1,2 out=roadsmajor_with_2_layers

It would be great if anyone could test it and if one of the devs could have a look at the patch and either apply it directly, or tell me that it's ok to do so.
