Comment 19 for bug 1280842

I'm a bit lost after the above comment. If there is a nesting-only bug I think it would be useful to describe that more concisely in a new bug report.

As for this enhancement request, it's still almost reasonable to just implement (comment #2). But we shouldn't do so while there appears to be bugs fuelling the motivation for the enhancement. Bugs should be fixed independently of the enhancement request.
