From 6c4f3ec9b477df534cd376f88618a57353f0f0fe Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 7 Aug 2009 15:45:30 -0700 Subject: [PATCH] verify-pack --stat-only: show histogram without verifying When this option is given, the command does not verify the pack contents, but shows the delta chain histogram. If used with --verbose, the usual list of objects is also shown.
