I can try to take a stab at it, but not being an Emacs hacker I just
barely understand the relationship between the reported bug and the
ultimate cause reported in the e-mail, nevermind the proposed work
around, that is indistinguishable from magic to me ;-)

I guess this means I may need some hand-holding, and at this point I'm
not sure that would be more work than actually making the changes.
Please advise.
