[PATCH] git-send-email: handle email address with quoted comma

[Wu Fengguang <fengguang.wu@intel.com>]

Correctly handle email addresses containing quoted commas, e.g.

	"Zhu, Yi" <yi.zhu@intel.com>, "Li, Shaohua" <shaohua.li@intel.com>

Here the commas inside the double quotes are NOT email separators.
