To ensure that the sources change, the trees need to be copied with the new source rather than preserving it.

I wonder whether there's not a less intrusive way to do it:
- In
Reposition, copy all leaf trees manually, usinguntpdconstructor methods instead ofcpy. - Then use the tree copier for the rest. That still needs
sourceFile, but we don't need to test for
sameSourceanymore.

I remember from #5892 there used to be a check sameSourceFile in the case, why it is not needed anymore?
