I spent some time today looking into what it would take to add the commit
number into the email.  Implementing this will add some extra complexity to the
emailer script and add another point of failure for us.  We also
can't guarantee to always have it since at some point we may want to start using
github's standard commit emails.

I think we should just wait and see how things go without having 
a commit number in the email.  It's easy to generate the number
locally from a git hash if needed.  If it becomes a major inconvenience
to not have it in the email, we can always look at adding it in later.
