Thanks, but ... hmmm.

Tried 0a43c802dd60f53d48136a32526a4b2a5f0d43e5..HEAD, just to get
another one :-( I guess this will go on a little while :-( Before I
start writing a script that performs this procedure findind a place
where it does work I'd like to share some history with you.

This started as a big project with a lot of history in CVS, including
moved (read deleted and re-created) files. This was moved to SVN and
from there immediately to GIT. In GIT lots of things have been renamed.
The RDF directory was created quite recent in the project and things
from various subdirectories were moved there.

Is there something that might be worth a try or should we go the simple
way: keeping the old combined repo for later reference and create two
new ones from fresh files?

	Cheers --- Jan
