Input (last checked 2014-12-26 09:01):
  * Fix ambiguous use of blockquote.
    Example: several lists marked as blockquote either lack bibliography
    or is not quotes (e.g. page 22).
  * Split "About" page:
    + "Copyright": Dry listing of copyright holders w/ years, licenses,
      online and offline contact info for Greens/EFA, and revision
      history. One paragraph for each part - Project owners, authors,
      designers, smaller contributors (photographer for coverpage).
      Check back side of title page for a few books to see common style.
    + "Preface": Short text about the creation and the people involved
      (i.e. like "About" but uncluttered from legalese).

Processing:
  * use Header (not latex RawBlock) as header markup in section filter.
  * Refine bibliography regarding web sources and timestamp markup.

  * Add quote filter to adjust custom *"foreign"* and "*title*" markup.
  * Cap over-long titles in headers.
  * Consistently place page numbers at bottom.

Content modelling:
  * Consider use typographic enhancement tunings:
    + icomma - avoid automagic space after comma (e.g. money amount).
    + ellipsis - ensure balanced space around ellipsis.
    + csquote (with explicit british: class ignored with polyglossia).

Styling:
  * Curly quotes.
  * Use standardized layout for bibliography.
  * no quoting around origin link string.
  * Add coverpage.
  * Add colophon to backmatter (brief facts on book design)
