 Current v.surf.* modules do not support breaklines (fault lines). It's
 common in geology and other fields to have line/surface that limits
 interpolated value expansion - interrupts spatial correlation
 (neighborhood influence).

 IMHO breaklines should be taken into account at two times - first when
 choosing data input points for calculation (only points at one side of
 line) and second time - when assigning values for cells - only cells at
 one side of line should receive values.

 I understand that this is longterm goal and it requires lot of discussions
 how it should be implemented. Still it's a wanted feature.
