I remember some headaches with this thread [1]. :-)

Well, it is probably unrelated because I guess the transformation makes
sense here but indeed you can have bad surprise if the transformation
does not make sense and then silently ignored.

Well, I have never finished my attempt to raise more information about
the transformation because the code about the transformation is hard to
follow, from my point of view.  Anyway!

Thanks for having open this ticket. :-)  Maybe with-source and
with-patch are the first incremental change. ;-)

Cheers,
simon
