Subject: [PATCH v3 1/3] send-email: move the read_config() function above getopts

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 9 May 2019 13:48:28 +0200

This is in preparation for a later change where we'll read the config
first before parsing command-line options. As the move detection will
show no lines (except one line of comment) is changed here, just moved
around.
