rerere mechanism with that?
If you know which merge I did you want to steal from, you can prime your
rerere database by pretending to be me, doing the merge. Something like:
$ git checkout $merge^1 ;# detach to the parent of merge
$ git merge $merge^2 ;# pretend you were me to redo it
$ git diff -R $merge | git apply --index ;# and get what I did
$ git rerere ;# have rerere record the resolution
