To me it doesn't make any sense that you would want to merge changes without looking at them first. It also seems very strange to me to treat not-yet-fetched branches on a remote the same as a local branch. I don't really have any useful input other than that you shouldn't assume what other people find intuitive, because you are usually wrong :). > Well maybe that exaggerates the point a little, git-merge is not that complicated, > but it is an additional command to learn with little benefit that I see. For me, git-pull is that additional command, and using git-pull . <branch> to merge feels really really strange.

The output of git-reflog is easier to read when you know what you're looking for, the actual commit message and author info that log outputs is usually superfluous. -- Mikael Magnusson -- 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
