I'm sorry.  I realized that I attached the wrong file.  And the line
number should have been 97, not 197.  Unfortunately, I cannot reliably
trigger the problem using the above recipe using a recent Emacs trunk
check-out.  Even more unfortunately, I have still encountered the
problem (but have been unable to recreate it).  All in all, though, I
think your changes have been beneficial.  I'll try to isolate an example
over the next few days.
