From b9b23b5b1586993eb313af2b058b0fbbaeb7fab1 Mon Sep 17 00:00:00 2001
From: srittau <srittau>
Date: Mon, 31 Dec 2001 20:01:17 +0000
Subject: [PATCH] Re-added const qualifier to the argument to parseline.
 Instead, introduce a new non-const tmp variable called tmpbuf. (Joe, you were
 half a minute quicker than I.)
