[PATCH] fix pack-object buffer size

From: Nicolas Pitre <nico@cam.org>
Date: Apr 20, 2006, 21:25 UTC
Message-ID: <Pine.LNX.4.64.0604201718000.2215@localhost.localdomain>

The input line has 40 _chars_ of sha1 and no 20 _bytes_. It should also account for the space before the pathname, and the terminating \n and \0.

I doubt anyone has ever used a repository with paths long enough to hit the limit, but better make it right nevertheless.
