If memory serves (which it might not), I think the consensus was that "branch" works just fine, and when someone who doesn't like it comes along we can just tell them that it's short for "tip-of-branch pointer", which is far more accurate. A "ref" is always local though, which is why the reflog (which is used for such date resolving problems) is never even considered to work on remote refs. They *can* work on remotes' refs though, which is a slightly different thing. Whatever, really. The fact that pretty much everyone seems to know what a branch is and how it works in git after a (very) brief intro to it means it's either right on target or that people are so used to the fact that branch means something different in every scm that they don't even bother loading the word with some preconceived notion that used to be right in cvs. -- Andreas Ericsson andreas.ericsson@xxxxxx OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- 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
