usr.bin/mail not SUSv3 compliant

    The mail patch needs to be functionally separated.  The
    minor syntactical cleanups have to be separated from the
    new options additions.  The reason for this is so other
    projects can review and pull in just the new options work.

    I recommend submitting the new options additions first,
    waiting for it to get into the tree, then submitting
    a cleanup pass.
