Thank you for the patch and I'm looking forward to hearing about how it
works for you guys.  I'd love to hear feedback from anybody else who is
trying this, too.

Everything looks good for stock configurations.  The ERROR_XXX_RESPONSE
constants should have "HTTP/1.1 " removed if used with this option, too.
That requires keeping track of whether or not we've written out
"HTTP/1.1 ", yet.

(I don't think there's much benefit in using constants for rarely-used
 error responses, either.  Most of those were inherited from Mongrel
 which had many client-triggered errors to deal with)

It should probably be done inside Unicorn::Configurator#commit!

"git apply" runs cleanly on this message :)

You'll probably find it more reliable and easier to use "git send-email".
The git-send-email manpage has an example for using it with
"git format-patch" + GMail SMTP.  Using "git format-patch" also lets
you preserve your original commit message/authorship information.
