Fix "git checkout -b foo ':/substring'"
Because ':/substring' extended SHA1 expression cannot take postfix modifiers such as ^{tree} and ^{commit}, we would need to do it in multiple steps. With the patch, you can start a new branch from a randomly-picked commit whose message has the named string in it. Signed-off-by: Junio C Hamano <gitster@pobox.com>
