Here are some patches to add a --remerge-diff capability to show & log, which works by comparing merge commits to an automatic remerge (note that the automatic remerge tree can contain files with conflict markers). Here are some example commits you can try this out on (with git show --remerge-diff $COMMIT): * git.git conflicted merge: 07601b5b36 * git.git non-conflicted change: bf04590ecd * linux.git conflicted merge: eab3540562fb * linux.git non-conflicted change: 223cea6a4f05

In regards to the performance point above, the timing for running the following command: time git log --min-parents=2 --max-parents=2 $DIFF_FLAG | wc -l in linux.git (with v5.4 checked out, since my copy of linux is very out of date) is as follows: DIFF_FLAG=--cc: 71m 31.536s DIFF_FLAG=--remerge-diff: 31m 3.170s Note that there are 62476 merges in this history. Also, output size is: DIFF_FLAG=--cc: 2169111 lines DIFF_FLAG=--remerge-diff: 2458020 lines
Which repo did you mean by linux.git? Kernel developers often work against Linus' mainline tree [1], while end-users (including myself) prefer stable tree (which is mainline + stable release branches and tags) [2].
