    doc/RELEASING: Fix the check for diffs from origin/master
    
    The recommended command to check for differences from master to the
    remote master was using git log with a range from the local master to
    the remote master but this wouldn't work if the local master is ahead
    of the remote master because the range is backwards. This patch
    changes it to recommend git diff --stat instead because then the
    command would work even if the two branches have diverged.
