Initial Comment:
There is a problem with v.segment side-offset parallel line generation for inside corners. It is in Vect_line_parallel(), so v.parallel, v.buffer, et al. are also affected. See it by doing the "-500" side-offset example in the v.segment help page and changing -500 to +500. Or do "v.parallel dist=500" using the railroads vector map.
