From 85f8d9da2182690461e05034a4a697f766bb8eb1 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 12 Nov 2018 15:25:58 -0800 Subject: rebase -r: do not write MERGE_HEAD unless needed When we detect that a `merge` can be skipped because the merged commit is already an ancestor of HEAD, we do not need to commit, therefore writing the MERGE_HEAD file is useless. It is actually worse than useless: a subsequent `git commit` will pick it up and think that we want to merge that commit, still. To avoid that, move the code that writes the MERGE_HEAD file to a location where we already know that the `merge` cannot be skipped.
