Finally I think you can make a distinction with silent "e", as Amanda
pointed out, but that's not possible in this case.  There's only one
other final /D/ after a short vowel in the language, that I'm aware
of; the question then is whether the spelling of "with" should be
considered regular or irregular.  I don't think there's any
indisputably correct answer to this question.

I quite agree.  I have no objection to people using "eth";  I only
brought up my reasons for preferring "edh" because Joe objected to
it.  I wouldn't want to give the impression that I think it's a
particularly important issue.
