* Intended modification target.

* suggested fixes of robot comments). For other modifications, the presence of a change edit
* influences their target. The latter comes from the REST endpoints of change edits which work no
* matter whether a change edit is present or not. If it's not present, a new change edit is created
* based on the current patchset. As we don't want to create an "empty" commit for the new change
* edit first, we need this class/interface for the flexible handling.
