be careful that moving a vertex a little bit in a location where the
units is meters might seem harmless but the same change in a lat/lon
location could be damaging. the location's projection units could just
as well be km, lightyears, ... too.

I would think it better to do the operation in 2 passes if some
cleaning is needed, and only fudge the data as a last resort.


maybe the v.clean remove small angles tool helps here.
