From 71234ec0bd16c490239eefcf98069ceb7a7f7618 Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <calcurse@cryptocrack.de>
Date: Wed, 16 Jul 2014 23:53:30 +0200
Subject: Refactor wins_launch_external()
Allow for passing an arbitrary number of arguments. This also allows us
to remove wins_launch_external2() and use wins_launch_external() at all
call sites instead.
