Find allout.el, go to the first heading (e.g. with the menu), use
Headings -> Toggle Topic Encryption from the menu, type `foo' as
passphrase and `bar' as the hint to get:

  ;;;_~* Provide
  -----BEGIN PGP MESSAGE-----
  Version: GnuPG v1.4.1 (GNU/Linux)
  
  jA0EAwMC4k9RaxuRboJgyRabxt2CW0in+vaRHnZ6jysmkDfz1KQ7
  =TImu
  -----END PGP MESSAGE-----
  
Use the toggle menu item again, and entering `foo' as the passphrase,
it says `Passphrase differs from established' and fails to decrypt
when I try again.  I did that test in Emacs 21 on Debian stable(-ish),
`gpg (GnuPG) 1.4.1'.  It was the same when I originally tried with the
development Emacs on Debian testing.

Oh.  I hadn't examined the keymap, but C-c x is reserved for users
according to the Lisp manual.  `allout-passphrase-verifier-handling'
appeared to be documented as controlling the behaviour.

No.  What, say, pgg-encode tries to do for an interactive call (which
is tested wrongly) can lead to data loss anyway since it doesn't check
that it's valid.  Check that with handa, since people accept what he
says.

See python.el for the example.  If it's not done in the installed
version, try <URL:http://www.loveshack.ukfsn.org/emacs/python.el>.  I
don't recall if I contributed that for the old python-mode.el, but I
couldn't get even the bugs in that fixed for use with Emacs.

I don't understand why the help text for allout-mode looks different
from what I remember before, but I don't have time or inclination to
understand it all, I'm afraid.  This was just an aside.
