No, the deviation file was not updated; it currently tries to write a
sites file which ends up with no attributes. So devi= is pretty useless
right now, until it is updated to 5.7 points.

Also I'd note that v.surf.idw still needs some updating. Currently it
only has field=, which is refering to column number not field value ..
