New description:

 Add an option to v.category option=replace that overwrites the cat values
 in a vector instead of only adding a cat to objects that do not already
 have a cat.

 Equivalent to

 {{{
 v.category input=input_vector output=tmp option=del
 v.category input=tmp output=output_vector option=add
 g.remove vect=tmp
 }}}

 Personally, I would also appreciate a flag [-r]?? or other mechanism to
 overwrite cats in the original vector (allow output=input).
