I think this script would be worth comitting as an example linked from
the user documentation, and maybe with a bit of commentary.  And
mention it in NEWS too.

It seems to me that they should be able to look at the output of  'bzr
status -r $OLD_REVID..$NEW_REVID' and 'bzr log -r $NEW_REVID'.  I'm
not completely sure if that will work in the context where the shell
hooks are run.
