[PATCH 2/3] git-multimail: Add a quiet option to prevent outputting email addresses from hook

[Dave Boutcher <daveboutcher@gmail.com>]

We have a very log list of recipients...displaying that list
on every push is annoying

Add an option to prevent printing the list of email addresses from
the hook
