I think that is an unnecessary complication for what is really a corner case. And anyway, it is just hacking around the fact that we don't really know what the remote side is if multiple branch heads have the same SHA1 as HEAD. You proposed a series a while back so that git could unambiguously determine what a remote symref points to, and I think that's the better way to fix this problem. If the user runs "git remote set-head -a <remote>" they will get whatever "git show <remote>" indicates is the remote HEAD. If they don't like that, they can set their <remote>/HEAD explicitly using the alternate syntax. j. -- 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
