Thanks for checking!

It seems to me that it isn't `diary-anniversary' that needs to be gotten
rid of, so much as `diary-sexp-entry' -- that's the function that's
basically just eval'ling a string. If I get rid of `diary-anniversary',
I'll basically just end up re-writing it.

At init time, instead of building up strings, I could just build up
closures holding the appropriate dynamic value for DATE and ENTRY, and
calling `diary-anniversary': essentially replace `diary-sexp-entry'.
That's at least one less layer.

I can get rid of the check for `original-date', but I'd still like to
know if we're in a calendar-marking situation vs a listing-the-diary
situation: how else would I do that?

Thanks again,
Eric
