IMHO the main problem in this case is NOT with the -f option, but rather that 'git push' defaults to pushing all "matching" branches. I'd much rather have push.default default to the much safer "tracking", which pushes at most one branch. But changing default behaviour is hard to do without annoying old-timers. I'm rolling out Git at my $DAYJOB to a few hundred developers, and I instruct them to git config --global push.default tracking immediately after installing Git. Which sucks, but is the only sane thing I can do to prevent this problem from haunting us. > By teaching the +refspec form, you force the user to be careful which > branch is rewound.

IME refspecs are not easily grasped by Git newbies, and the longer they can get by without having to learn them, the happier they'll be with Git. IMHO, refspecs are really cool and powerful, but you shouldn't have to learn them in order to do day-to-day development. ...Johan -- Johan Herland, <johan@xxxxxxxxxxx> www.herland.net -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
