We batch in five minute intervals but comments mark the boundaries
between batches, so if you make a bunch of changes and add a comment
and then someone else makes a bunch of changes you'll get two separate
notifications. Attachments cause problems because they each get their
own comment, so we send out one notification per attachment. Otherwise
our batching is quite sane at the moment.

We *might* be able to move to five-minute digests when we've fixed all
the Launchpad-fakes-email-addresses bugs. The easy fix to some of
those bugs is to start to use <$<email address hidden>> as the From
address for notifications and if we do that we may be able to change
notification emails to look like this:

 From: Bug $FOO <$<email address hidden>>
 ...
 ** Graham Binns (gmb) made the following changes
   * In Ubuntu:
     * status Incomplete -> Confirmed
   * Comment added:
     This new digest thing is the bomb isn't it?

 ** Deryck Hodge (deryck) made the following changes:
   * In Malone
     * status Incomplete -> Fix Released
   * Comment added:
     Yeah, it's not bad.

But I'm not yet convinced that there would be a massive reduction in
bug mail traffic if we did that, or at least not a reduction directly
related to the batching of attachment notifications.
