 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.

 Shouldn't the multi-import dialog be written for GDAL/OGR format instead
 of file name extensions? Multiple raster import using GDAL imports several
 raster bands from several datasources at once, while multiple vector
 import using OGR imports multiple vector layers from only one datasource
 in case of e.g. shapefiles and multiple vector layer from multiple
 datasources in other cases e.g. gpx or kml. Although the two dialogs look
 identical, they behave different, and for multiple vector import,
 behaviour depends on the selected OGR format. BTW, multiple raster import
 also uses the term layer whereas it's datasources that are listed, the
 layers (raster bands) are not listed.

 I agree, no changes in relbr6, anyway multiple import of vector data has
 already been possible with both v.in.ogr and the multiple vector data
 import dialog. I'm just not happy with the restriction to certain GDAL/OGR
 formats and undocumented behaviour of the two multi-import modules.
