- it will blame the modifications of merged cherry-picked commit
to only one commit. Without the option parts of the modification
will be reported as coming from the one, parts will be reported
to be from the other. With the option only one of those two commits
is reported as the origin at the same time and not both.
- it is more predictable which commit is blamed, so if one is
interested in where some commit was introduced first into a
"mainline", one gets this information, and not somtimes a different
one due to unrelated reasons.

While the result is more consistent and more predictable in the case
of merged cherry picks, it is also slower in every case. Usually speed
will be more important than this exactness, especially as the result
will not differ for the common case (if there are no cherry-picked
commits merged or when those commits do not touch any files that are
otherwise only modified in the merged branch).
