[PATCH 01/10] revert: free msg in format_todo()

[Ramkumar Ramachandra <artagnon@gmail.com>]

Memory allocated to the fields of msg by get_message() isn't freed.
This is potentially a big leak, because fresh memory is allocated to
store the commit message for each commit.  Fix this using
free_message().
