Two kinds of commit are qualified as a parent:
 1. The commit touch some lines of the current

 2. The commit is a merge commit.

So, there will be more commits output than the
situation which parent rewrite is not set on.

Sorry, but -ECANTPARSEATALL.  What do you mean by "qualified" and in what
context?  What makes these two conditions significant?
