There is a start and a end, don´t merge into the middle
Assuming we are taling about git. How can you merge to the wrong repo? You mean the wrong remote repo?
Yes, we have 5 times the same repo, because of security or something. You are supposed to merge from 0 to 4. If you merge 2 commits into 3 and another one into 4, we are going to have a little problem.
That's the dumbest solution ever.
I know that you are probably not the one who came up with this shit but just... why? Why would you do that?
Don't you know that git has so called branches?
