It's really surprising specifying > -p has no visible effect. That's because "-p" is already the default, and the format selection is orthogonal to the handling of merge commits. Providing "-m" would actually override the "--cc" default (though "--first-parent -m" is likely to be less noisy, per this discussion). As far as defaults go, I dunno. The idea is that "--cc" would give you a nice summary of what the merge _itself_ had to touch. I think that's valuable, too. If we were starting from scratch, I think there could be a discussion about whether one default is better than the other. But at this point I have a hard time finding one so much obviously better than the other to merit changing the behavior. > Also, is current output of "git log -m", being extremely confusing, > suitable for anything?

I've used "-m" without "--first-parent" sometimes in order to track down mis-merges manually. It's not usually a big deal to say "--first-parent" if that's what you want. But one thing I don't think is currently possible is to ask only for the first-parent diff, but _not_ restrict the actual traversal. If that's what you mean by giving an argument to "-m", then yeah, I think that would be a useful addition. -Peff
