OK; I've now adjusted the patch with those two things...

... and that is indeed the major problem here -- this is an area where
it's very difficult to test all the use cases, and Emacs behaves
differently here on different systems.

I think the only realistic way to get some testing here is to just push
it to the trunk and see whether people report issues, unfortunately.
(The patch works fine on this Debian system, at least, and Ulrich
reports the same, so we have at least two systems it works on.  :-))

So I'll push the patch and we'll see whether there's any fall-out...
