From ae0e4711503c4a37fccc12e6cfd74c0cc3108d0a Mon Sep 17 00:00:00 2001
From: Robert Peichaer <rpe@cvs.openbsd.org>
Date: Wed, 26 Dec 2012 10:38:11 +0000
Subject: Combine almost identical code for fetching and checking of the
 etcXX.tgz/xetcXX.tgz sets into a more generic function get_sets(). Move the
 SRCDIR check into the getopts while-loop as well.
