I don't see any good reasons to describe in the manual something that is different from the reality, I think this could only add to confusion. Backtraces are usually "ugly" in that way, and developers should get used to that. If you or someone else have ideas how to make this "nicer" without lying to the reader, I'm all ears. Thanks.
