[PATCH v4 0/2] git-multimail: a replacement for post-receive-email

[Michael Haggerty <mhagger@alum.mit.edu>]

This is the fourth iteration submission of git-multimail to Git.  The
earlier submissions have all gotten a lot of good feedback, which has
mostly been implemented.  This submission differs from v3 in the
following ways:

* Renames the directory within the Git project from
  contrib/hooks/git-multimail/ to contrib/hooks/multimail/.  The
  "git-" seems redundant within the Git project [1].  I have no strong
  feelings either way.

* Includes the latest version of the upstream project.  Highlights:

  * A change in how git-multimail is configured via Python.  I wasn't
    happy with the old method; concerns were not separated well
    enough.  I wanted to get this right before more people start
    writing against the internal API.  The new version uses mixin
    classes, which is a technique that can easily be overdone.  But in
    this case I was happy with the way that it permitted different
    aspects of the configuration to be disentangled quite well.  (This
    doesn't change how the script is configured externally via "git
    config"; that has been stable for quite some time already.)

  * Fixes a scalability issue for repos with lots of refs that was
    pointed out by Ævar Bjarmason.

  * Allows an arbitrary program to be substituted in place of
    /usr/sbin/sendmail when using the SendMailer.

  * Improvements suggested by Ramkumar Ramachandra's code review
    (thanks!).

  * Various documentation improvements.

* Adds a new file, README.Git, which explains the relationship between
  the Git and git-multimail projects, and documents the version of the
  upstream project that corresponds to the code being submitted to the
  Git project.

* Adds a notice to contrib/hooks/multimail/post-receive deprecating
  that script and pointing users to git-multimail.

The upstream project also now includes better tests.  Though I am not
including the tests in the code submitted to the Git project,
obviously the code benefits from them.

[1] I also got the feeling that Junio prefers the new directory name,
    though there is a good chance that I read more into one of his
    emails than he intended.
