From 42ae63a25ca45c613277315973dee6377fa6ba9c Mon Sep 17 00:00:00 2001
From: Hans-Christoph Steiner <eighthave@users.sourceforge.net>
Date: Sun, 11 May 2008 13:26:08 +0000
Subject: created sys_expandpath() to replace ~ with /Users/hans and expand env
 vars on Windows.  This function is then used in sys_trytoopenone() so that ~
 works with all opening operations.
