This is the opposite of git-rev-list --no-merges: It will hide commits with single or no parent.
It is useful if a maintainer has a lot of commits between tags and usually each feature is developed in its own topic branch.

I just wanted to see the list of merges since the last tag in a repo where we have 1000+ commits and about 20 merges and found that there is no easy way to do so.
As a side effect, git rev-list --no-merges --only-merges will list nothing, but that's logical IMHO.
