Do it, if you think it is appropriate. I now Markus had done some
ambiguous commits (probably to show "progress") some of which have
been reverted by other devs. He has leaved the project in
September, 2015.

I'm sorry for the private (and probably late) email, just don't
want to ignite a flame on geda-user.
