[GRASS-dev] Vectlib: delete broken vectors upon creation failure?

[Huidae Cho]

Is there any way to know from the library if a map has not been completely
imported?  IMHO, incomplete import is different from corrupted files (well
sometimes it could mean broken vectors), so only modules importing files can
determine to remove incomplete vectors.
