Hi All, When I merge branch A back to master branch,if there are same commit(developer do double commit) both in master and A branch, there will be two same commit in master branch.For example 1->2->3-4>5 Master | 4->6->7 A When I merge A branch into master,the two same 4 commit will present in master branch. Is there any wrong with my operation?
