Thanks for the reply. This variable is just what I need. C-h v
indicates that it is not present in the version of gnus that I have
(see 3, above). Do I just grab an arbitrary nightly snapshot  and
replace my lisp/gnus folder? Or will this introduce more
"instabilities" than it is worth? Or am I better off downloading and
compiling a newer emacs? If so, which version will suffice? Is there
an FAQ about this?

Thanks again for your patient replies,
