 Currently, v.buffer only allows a column selection for single radius (opt
 "column"), but allows the creation of "oblong" buffers using the manual
 entry opts "distance", "minordistance", and "angle". v.buffer would be a
 lot more useful if these could all simply be column selectable too. For
 example, if I have a large vector points file of archaeological site
 locations, and I have BOTH a length and width column (and, potentially, a
 "site axis direction" column too), then I could make a "buffer" map of the
 actual site size and orientation. Currently, in v.buffer, I can only use a
 calculated "average" site radius column, and make circular buffers for
 these sites.
