attached is a patch and ChangeLog for a substantial new version of
allout.el, emacs' alternative (and much more extensive) outliner.  i
think it's ready to revise the distributed version.

this version adds topic encryption, using GPG.  it also includes
several fixes and enhancements, described in the ChangeLog entry

below is the synopsis of just the encryption features, from the ChangeLog entry.

	  - new subsystem supporting easy gpg topic encryption/decryption.

	    salient features:

	    - both public- and symmetric-key modes are supported.
	    - encryption being on a per-topic basis means you can
	      intersperse encrypted and clear-text data in a single file
	      to your heart's content.
	    - user-provided symmetric-key hints, with consistency
	      verification to help user avoid confusion
	    - time-limited key reuse, a la (and using) mailcrypt's
	      mc-passwd-timeout
	    - write-file-hook and auto-save-hook activities to support auto
	      encryption of pending topics on save; provision to skip
	      currently-edited topic to avoid editing disturbance

	    topic encryption functionality depends on both mailcrypt and
	    crypt++ packages.  (non-encryption allout functionality is not
	    disrupted if either mailcrypt or crypt++ are absent.)

	    `allout-toggle-current-subtree-encryption' is the central
	    routine.

	    there are a five new encryption customization variables:

	    - allout-topic-encryption-bullet
	    - allout-default-encryption-scheme
	    - allout-key-verifier-handling
	    - allout-key-hint-handling
	    - allout-encrypt-unencrypted-on-saves

	    topic encryption is included in mouse menu

	    docstring for `allout-toggle-current-subtree-encryption'
	    and customization variables provide detailed description.
