OK, this doesn't really need any hooks at all (the tip-bot is not a
hook).  The committer is, and *has to be* responsible for getting the
unique string into the Link: tag, through whatever means they feel is
appropriate.

Based on the previous message, I'm going to modify the bot to recognize
the pattern:

Link: http://lkml.kernel.org/r/tip-`ranpwd -l 24`@....kernel.org

... to override the Message-ID.  It seems like the least ugly of a lot
of ugly options.
