?  Sorry; I didn't understand the above.  Are you saying I personally
would be tempted to do that, or that in the abstract one would be
tempted to do that?

How would the user hook in to run the sort, unless we provide some
option in saveplace.el?  (We don't generally expect users to modify the
source code of core Emacs packages.)

Um.  Can you say the above more verbosely?  I'm not really understanding
how many different topics you're addressing, nor what changes you're
proposing... I'm happy to address a concrete proposal, I'm just having
trouble understanding exactly what you're saying above.  (It could be
because I'm a bit sick right now; apologies if my brain isn't working
right...)
