[PATCH] git-send-email: fix handling of special characters

When patch sender's name has special characters,
git send-email did not quote it before matching
against the author name.
As a result it would produce mail like this:

	Date: Thu, 23 May 2013 16:36:00 +0300
	From: "Michael S. Tsirkin" [off-list ref]
	To: qemu-devel@nongnu.org
	Cc: "Michael S. Tsirkin" [off-list ref]
	Subject: [PATCH 0/9] virtio: switch to linux headers
	Message-Id: [off-list ref]

	From: "Michael S. Tsirkin" [off-list ref]

Fix by sanitizing before matching to patch author name.
