File libesmtp-1.0.4-multiple-cc.patch of Package libesmtp

From: Bernhard Walle <bwalle@suse.de>
Subject: [PATCH] Allow multiple Cc and Bcc header calls

This patch modifies the library so that smtp_set_header() can be called
multiple times. One header will be generated with a comma-separated list
of values.

That's the behaviour as described in the API documentation at
http://www.stafford.uklinux.net/libesmtp/api.html.
