[PATCH 1/3] email-sh-functions: make merge addresses work on multiple line inputs

[Jacob Keller]

This minor change fixes merge_addresses so that it can be used with
multiple line inputs. Basically this lets use ues formail to get the
address from multiple headers, and correctly merge the list into a comma
seperated value.

The primary usage for this change will come in a future patch which
introduces a method for getting the address out of multiple Cc headers.
