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.

* As we advertize that ":/string" syntax is usable for any
command that wnats to take a commit object name in the
Release Notes, we might want to put this in 1.5.4 final. It
looks simple and safe enough.
