Subject: [PATCH] Fix a comparison bug in diff-delta.c

From: Pierre Habouzit <[email-masked]>
Date: Wed, 23 Aug 2006 11:17:55 +0200

(1 << i) < hspace is compared in the `int` space rather that in the
  unsigned one.  the result will be wrong if hspace is between 0x40000000
  and 0x80000000.

  This is a replacement for <[email-masked]>
  avoiding the ugly cast, and using 1u instead.
