You colleague is most likely correct. I suggested it as this is a one time operation and therefore still somewhat practical from my point of view. If you don't like the solution then you need to change the git-svn code. Probably here somewhere (I am not familiar with this code): https://github.com/git/git/blob/master/git-svn.perl#L1836 - Lars PS: Please don't top post on this mailing list :-) https://en.wikipedia.org/wiki/Posting_style#Top-posting > > Paul Mattke > Software Developer > ------------------------------------------------- > Arvato Systems S4M GmbH > Am Coloneum 3 > 50829 Köln > > Phone: +49 221 28555-443 > Fax: +49 221 28555-210 > E-Mail: paul.mat...@s4m.com > www.s4m.arvato-systems.com > > > -----Ursprüngliche Nachricht----- > Von: Lars Schneider [mailto:larsxschnei...@gmail.com] > Gesendet: Dienstag, 20.
