[PATCH 1/7] revert: Free memory after get_message call

[Ramkumar Ramachandra <artagnon@gmail.com>]

The format_todo function leaks memory because it forgets to call
free_message after get_message.  It is a potentially big leak, because
fresh memory is allocated to store the commit message message for each
commit.  Fix this.
