I've been repeating the above to new people to save you time, but recently I noticed one thing. The handling of a case where a pull decides to go ahead (because it does not have to touch the Makefile you have your codename updates in) but does not complete with real conflicts, is not as graceful as the other two cases (merge refusing to run at all without touching anything, or merge completes cleanly and makes a commit). You will be left with: - Paths that have local changes (index matches HEAD but work tree does not match the index --- like your Makefile); - Paths cleanly merged (index and HEAD are different but work tree already matches the index); - Unmerged paths (index has higher stage entries with <<</===/>>> files in the work tree); You, I and experienced users know what to do. Deal *only* with the last kind, mark them with "git add" after you are done with each of them, and make sure you do not say "-a" when committing the result, to exclude the first kind from the merge result. I've been wondering if we can make this safer for others. -- 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
