Thank you for the suggestion, Stefan. I've looked at desktop-save-mode in the
past, but I haven't tried it. From what I recalled, it seemed to save and
restore things which I don't really want restored (like variables?!), and I
think it only works with a single session. But maybe I can fix that by
changing the desktop-save-mode save file on a per-host basis. I'll look into
it further.

I still don't think the auto-save-list-file-name file should be deleted on
SIGHUP, but I won't be offended if you close this bug as "won't fix" or some
such, assuming you all disagree.

Regards,
Ed
