I was fiddling with pcs.csv, gcs.csv and corresponding override files in and
managed to get the system into such state that piecewise reprojecting from
epsg:2393 to 3067 by making a temporary epsg:4326 version in between gives
correct result, while direct reprojecting from 2393->3067 gives a different and
faulty result. My conclusion is to forget the csv files and continue to use
+proj strings for giving projections to ogr2ogr. It is not handy but it is
reliable and I know for sure what is going to happen.
