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

[Markus Neteler]

Hi,

Huidae had added the nice feature in v.in.dxf (now functional, I guess)
that a broken vector map is immediately removed when import wasn't
successful and is not left behind.

This is an issue which affects various modules. I think we should
add this somehow to the vector library since broken vector maps
aren't really useful. The tmp file approach of raster maps is
more failsafe here. Since tmp doesn't exist for vector maps,
any ideas how to implement that?
At least v.in.ascii needs it, maybe also v.in.ogr.

Markus
