Comment:

 But if dsn points to a shapefile directly and layer is omitted, only this
 one shapefile is imported. And a directory may hold only one shapefile, so
 only one layer would be imported anyways.

 Alternative: have a new -a flag to import all layers in given dsn. Without
 -a flag, if only one layer is found, import it, if more layers are found,
 list them (same like -l flag) and exit with a helpful message like "Please
 select layer to be imported or import all with -a". I would like to
 preserve the possibility to import all layers in a given (file-based) dsn,
 e.g. a *.gpx or *.kml file, but since the most common usage seems to be
 importing one OGR layer only, importing several OGR layers into one GRASS
 vector map could be triggered by this new flag. Disadvantage is that this
 adds yet another option to v.in.ogr.
