Revision 41e86a377496231709a5fb78df730df7be80b6c9 authored by Caio Marcelo de Oliveira Filho on 26 February 2008, 02:14:31 UTC, committed by Junio C Hamano on 26 February 2008, 05:43:37 UTC
Since commit 8c1ce0f46b85d40f215084eed7313896300082df filter-branch fails when a <command> has a non-zero exit status. This commit makes it clear in the documentation and also fixes the parent-filter example, that was incorrectly returning non-zero when the commit being tested wasn't the one to be rewritten.
