Whenever I attempt to M-m a mail bounce, I get the message
	Cannot parse this as a failure message

So I finally got round to looking into why (and it turns out to be that
the value of mail-unsent-separator doesn't match anything in our rather
non-standard mail bounce format -- on which I'll hassle our local mail
Gurus).  On the way, I came on a failure of the help mechanism, a
documentation error and a pertinent omission from the info pages.

I don't get any help out of C-h C-f rmail-retry-failure, 'though I am
able to find the relevant info-page by hand.  In this there is a
grammatical glitch:
>	The `To' field is starts out as the address ...
<	The `To' field is initialised to the address ...
(or similar).  However, there was no help towards my problem.  I duly
hunted in the emacs lisp directory for rmail-retry-failure and found it
in rmail, where I duly spotted that what mattered was the value of
mail-unsent-separator.

It would be worth extending the documentation of rmail-retry-failure to
include mention of mail-unsent-separator, preferrably explaining how I
(or someone less familiar with regular expressions) can go about
changing it to include my local mail system's choice of bounce-format.
This would optimally be changed by the emacs installation bod (ie me, on
our site) in the site-init rather than in personal init files.

While I'm on the topic, IWBNI activation of iso-accents-mode to compose
a message would prompt it to insert whatever is the valid something like
	Content-Type: text/plain; charset=ISO-8859-LATIN-1
in the header.  I have no idea how to do this nor what is the correct
thing to put in the header.

Thanks for a system which does marvelously nearly all the time ...
