Questions about branching in Mercurial

In the 'git' User Manual I've found this:

"Normally a merge results in a merge commit, with two parents, one 
pointing at each of the two lines of development that were merged.

However, if one of the two lines of development is completely contained 
within the other -- so every commit present in the one is already 
contained in the other -- then git just performs a fast forward; the head 
of the current branch is moved forward to point at the head of the 
merged-in branch, without any new commits being created."

I think this is exactly what is missing in Mercurial as of now. I would 
appreciate if you could add it.
