Dylan,

Thanks for your feedback. If you could give it some testing and let me
know how it works for you I'd be very gratefull.

I have used it on some of my data and all looks ok. I'm wondering
tough how copying the table from input to output would behave in case
of vectors with table stored in Postgres or Mysql (I'm using only dbf
or sqlite). I did my best to make table copying possible for any DB
backend, but this needs to be checked in action.

I would be great if Grass maintainers find the script good enough to
be included in the main distr.

Best,
Maciek

P.S.
Regarding the v.digit replacement currently being worked on, I believe
that an *interactive* lines direction flipping would be a nice feauture.
