Should we think about adding some commands for that ?
On the very top of my head (there is certainly more than that):
- Save such a change: By basically creating a ref to HEAD (HEAD being
the commit, HEAD^ the fixed merge) with merge-fix/HEAD^^1-HEAD^^2
- Apply the merge-fix: On top of a merge, find the most recent
merge-fix for HEAD^1/HEAD^2 (according to what was discussed), and
