Hi,

I don't know what you expect by "logical" nor if I get you right, but if fast-forward merge a branch to another one, both branches now have exactly the same hash. If you create a commit object for a fast-forward merge, both tip hashes not identical anymore... which is bad.

The identical hash important so that you really know they're identical and for future reference like ancestry.

   bye, Rocco
