 There is a user interface change to v.parallel in GRASS 6.x. The option
 `distance' does not accept negative offsets anymore, and introduces a new
 `side' option to distinguish left/right, instead.

 Before v.parallel2, v.parallel used to accept negative numbers for dist.
 Now it fails:

 {{{
 $ v.parallel in=lines out=lines_par dist=-1

 ERROR: value <-1> out of range for parameter <distance>
        Legal range: 0-100000000
 }}}

 I guess such a change to user interface within a stable release line is
 not allowed.
