Christian Couder a17c410100 Bisect: implement "git bisect run <cmd>..." to automatically bisect.
This idea was suggested by Bill Lear
(Message-ID: <17920.38942.364466.642979@lisa.zopyra.com>)
and I think it is a very good one.

This patch adds a new test file for "git bisect run", but there
is currently only one basic test.
