Using Emacs ediff as a Bazaar change editor

[Ben Finney]

Howdy all,

I tend to use Bazaar from the command line, in a GNU Screen session,
usually without X access from that session. In another GNU Screen window
in the same session, I use Emacs as the editor, and enjoy its ‘ediff’
mode.

With recent talk about using an editor for resolving changes in Bazaar,
I'd like to know:

* What different Bazaar operations benefit from a change editor?
  Resolving merge conflicts; selecting hunks to shelve; viewing diffs;
  anything else?

* How can I best invoke (text-mode) ediff as a Bazaar change editor
  command? <URL:http://www.emacswiki.org/emacs/EdiffMode> discusses many
  variations of this, but I am hoping this is a solved problem in the
  Bazaar context.

* Which ediff invocation is appropriate to each of the corresponding
  Bazaar operations above? I think ‘ediff’ would be best for viewing
  diffs, but ‘ediff-merge-files-with-ancestor’ for resolving conflicts,
  for example.
