Make sure titles are not redundant with breadcrumbs

The logic for the various titles on any given page is:

    ∃README
        ∃title block
            <title>         ⇒ title block
            <header> <h1>   ⇒ title block
            TOC <h1>        ⇒ "Index for {target}"
        ∄title block
            <title>         ⇒ "{target}" or "README"
            <header> <h1>   ⇒ ∅
            TOC <h1>        ⇒ "Index for {target}"

    ∄README
        <title>         ⇒ "Index for {target}"
        <header> <h1>   ⇒ "Index"
        TOC <h1>        ⇒ ∅
