From e2e5e98a40d6ed04b7acf791cc2243ff32923db3 Mon Sep 17 00:00:00 2001 From: Petr Baudis Date: Wed, 13 Apr 2005 01:40:09 -0700 Subject: [PATCH] [PATCH] Silent flag for show-diff This patch adds a -s flag for show-diff, which will surpress the actual diffing. This is useful for my scripts when they just want to see what needs to be updated in the cache.
