 default?

 I would keep this behaviour for GRASS 6.4. In GRASS >= 6.5 there are
 options and user can decide if to override check or not.

 dataset projection by default may be a bit dangerous. Having that option
 for v.external would be a good idea.

 OGR datasources, for e.g. *.gpx and *.kml files, datasources are listed as
 layers, although these datasources hold layers themselves. With so many
 different supported OGR formats, I would strongly opt to at least stick to
 the terminology used by OGR in regard to what is a datasource and what is
 a layer to avoid user confusion.

 name". What is listed there can just as well be OGR datasources not
 layers, and within these OGR datasources are layers not listed in the
 wxGUI dialog. It seems that this dialog is written for shapefiles, not
 sure how to use that with e.g. kml, gpx, postgresql if the idea is to have
 a separate output vector map for each layer.

 Right, dialog was written for shp/tiff/dxf. Should be improved at least in
 GRASS 7. I would suggest to close this ticket as worksforme for 6.4.0.
