Subject: [PATCH v4 13/21] ident.c: read /etc/mailname with strbuf_getline()

From: Junio C Hamano <[email-masked]>
Date: Thu, 14 Jan 2016 15:58:28 -0800

Just in case /etc/mailname file was edited with a DOS editor,
read it with strbuf_getline() so that a stray CR is not included
as the last character of the mail hostname.

We _might_ want to more aggressively discard whitespace characters
around the line with strbuf_trim(), but that is a bit outside the
scope of this series.
