I've merged a project from my abc branch to my xyz branch. I'm used to add the flags no-commit --no-ff in order to view all changes and approve them before commiting and pushing. So I received like 6 changed files from this merge, I reverted 3 of them and used the remaining 3 as my merge commit.
Now I want to repeat the operation, retrieving once again these 3 files from abc branch. But whenever I run git merge abc --no-commit --no-ff, I don't get the 3 chnged files anymore.
How can I ignore this past merge and see everything that is different between my 2 branches?
