Thank you.  I will give that a try.  It may turn out to be a nuisance,
tho, that it requires inserting the character in the current buffer &
then deleting it.  The function I defined is usually run in the
background, and it might cause confusion in that it would cause the
current buffer to be marked as modified, and might interact oddly with
my keying.  What I would really like is an append-to-file command that
takes as its argument an arbitrary character or string, rather than a
substring of the current buffer.
