I think we should at least do something like the patch below. I do have a dream that one day we'll be able to represent conflict resolutions over email, but we're not there yet. Likewise, it might be reasonable format-patch to issue a warning() when it is ignoring a merge. Or maybe some people would find that annoying (e.g., because they don't care about back-merges from upstream that happened during the development of a topic). But I think this documentation change is easy and hopefully uncontroversial. -- >8 -- Subject: [PATCH] docs/format-patch: mention handling of merges Format-patch doesn't have a way to format merges in a way that can be applied by git-am (or any other tool), and so it just omits them. However, this may be a surprising implication for users who are not well versed in how the tool works. Let's add a note to the documentation making this more clear.
