IIRC, Peff's "first-parent implies 'm' but can be countermanded with --no-diff-merges" defines "implication" exactly that way. I do not think that is a recent invention but it is just following the patterns set by other options that has conditional implications. IOW, $ git log --no-diff-merges --first-parent -p next $ git log --first-parent -p --no-diff-merges next should both mean the same thing. The user said no patch is wanted for merge commits with --no-diff-merges and --first-parent does not affect it.
