[sup-talk] a couple highlights in next

[William Morgan]

Hi all,

Here's a summary of all the fun stuff that's currently merged into the
next branch:

- zsh completion for sup commandline commands, thanks to Ingmar
  Vanhassel. (zsh-completion)

- Undo support for many commands, thanks to Mike Stipicevic.
  (undo-manager)

- You can now remove labels from multiple tagged threads, thanks to
  Nicolas Pouillard, using the syntax -label. (multi-remove-labels)

- Sup works on terminals with transparent backgrounds (and that's fixed
  copy-and-paste for me too!), thanks to Mark Alexander.
  (default-colors)

- Pressing 'b' now lets you roll buffers both forward and backward,
  also thanks to Nicolas Pouillard. (roll-buffers)

- Duplicate messages (including messages you send to a mailing list, and
  then receive a copy of) should now have their labels merged, except
  for unread and inbox labels. So if you automatically label messages
  from mailing lists via the before-add-hook, that should work better
  for you now. (merge-labels)

- Saving message state is now backgrounded, so pressing '$' after
  reading a big thread shouldn't interfere with your life. It still 
  blocks when closing a buffer, though, so I have to make that work.
  (background-save)

- Email canonicalization, also thanks to Nicolas Pouillard. There's been
  a long-standing problem in Sup where names associated with email
  addresses are saved and reused. Unfortunately many automated systems
  like JIRA, evite, blogger, etc. will send you email on behalf of
  someone else, using the same email address but different names. The
  issue was compounded because Sup decided that longer names should
  always replace shorter ones, so receiving some spam claiming to be
  from your address but with a random name would have all sorts of crazy
  effects.
  
  This should now be fixed. The mapping is no longer maintained.
  Addresses are still stored in the index, both for search purposes,
  and for thread-index-mode. (Otherwise thread-index-mode has to reread
  the headers from the message source, which is slow.) Once
  thread-view-mode is opened, the headers must be read from the source
  anyways, so the email address is updated to the correct version.
  
  So, incoming new email should be fine. Sup will store whatever
  name is in the headers, and won't do any canonicalization.

  For older email, you can update the index manually by viewing the
  message in thread-view-mode, and forcing Sup to re-save it, e.g.
  by changing the labels and then changing them back. Marking it as
  read, and then reading it, should do the trick, at least for read
  messages.

  You can also make judicious use of sup-sync to do this for all
  messages in your index.  (dont-canonicalize-email-addresses)
