To allow further flexibility in the git hook, the smtp header
information of the email that git-send-email intends to send, is now
passed as a 2nd argument to the sendemail-validate hook. A new t9001
test was added to test this 2nd arg and docs are also updated.
As an example, this can be useful for acting upon keywords in the
subject or specific email addresses.

~~~~~~~~~~~~~~~~~~
-This hook is invoked by linkgit:git-send-email[1]. It takes a single parameter,
-the name of the file that holds the e-mail to be sent. Exiting with a
-non-zero status causes `git send-email` to abort before sending any
-e-mails.
