you are right, medium_delete is only for deleting unused media
definitions.

There were already many questions also mentioned to me and I forwarded
this wishes to the development but so far there is no solution for
steady growing backup histories. Especially database users which do
hourly log backups get huge histories in a very short time!

Some couldn't wait for an official tool and started to delete manually
entries in the history files but this is a little bit more complex than
to delete lines in one file. Instead, as far as I know, up to three
files has to be manipulated in a consistent way so that you don't loose
the very important backup history.
So, please be careful.

But maybe this list can help to get a simple functionality here :-) ...
