[PATCH] recursive-merge: Don't print a stack trace when read-tree fails.

From: Fredrik Kuivinen <freku045@student.liu.se>
Date: Sep 25, 2005, 14:48 UTC
Message-ID: <20050925144824.GB20527@c165.ib.student.liu.se>

If the working tree is dirty read-tree will fail, and we don't want an ugly stack trace in that case. Also make sure we don't print stack traces when we use 'die'.
