If it the latter, that's a problem.  If it is the former only, then it
would be more like an Aquamacs problem.

I am not sure.  I think that this code may be mostly historical, so it
is possibly hard to find somebody who has a good idea about it.  I think
we may have dabbled in the code somewhat, but more or less on a "poke it
until it seems to work" basis.
