Provide better instructions on commit-msg failure

Modify on the technique introduced in #519 to instead provide clear
instructions on how to re-attempt your commit message starting from the
one you previously had.

This reduces large amounts of output pasted to the terminal, and is
instructional to users who aren't familiar with this feature of Git.

Now commit-msg failures will be followed up with:

    Try again with your existing commit message by running:
    git commit --edit --file=.git/COMMIT_EDITMSG

The reason we don't attempt to simply re-open the editor is that by the
time we've failed the hook, Git has already decided the run has failed
and there is no means of recovery.

Closes #651.
