 this was bug # over on the old gforge tracker. moving it here.



 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.
