Hi,
the patch below fixes preparation of commit block in
journal_write_commit_record(). Obviously the bug doesn't really matter
since nobody reported it so far but let's cleanup the code... Andrew, could
you please queue it up? Thanks.

Commit block is expected to have several copies of the header. Fix the
bug Andrew has spotted ages ago.
