[PATCH 1/3] Fix post-receive hook to not update the previously pushed commit

[Carl Worth]

Previously, the post-receive hook would always examine one commit that
had been previously pushed, (when the purpose of the hook is only to
example newly-pushed commits). We fix this by simply dropping the '^'
in the commit-range specification.
