The problem with v.breach is down to v.parallel interface change in
v.parallel2 - option `distance' does not accept negative offsets
anymore, and introduces a new `side' option to distinguish left/right,
instead:

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

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

@Devs: It would be cool if v.parallel could be changed to accept
negative offsets, for compatibility within 6.x line.

@Luís: I applied most your of patch. Thanks! Are you sure that's all
errors? I keep on getting warnings like:

WARNING: Unable to get point on line: cat = 1 offset = 2.831711 (line
          length = 0)

at v.segment calls in the script, and a crash at v.in.ascii.

Best,
Maciek
