Revision 18afe101eb2c2f68ba58085515f592148128fba3 authored by Martin Koegler on 10 November 2008, 21:47:11 UTC, committed by Junio C Hamano on 11 November 2008, 23:26:40 UTC
Current git versions ignore everything after # (called <head> in the following) when pushing. Older versions (before cf818348f1ab57), interpret #<head> as part of the URL, which make git bail out. As branches origin from Cogito, it is the best to correct this by using the behaviour of cg-push, that is to push HEAD to remote refs/heads/<head>.
