Article Highlighting
--------------------

   Not only do you want your article buffer to look like fruit salad,
but you want it to look like technicolor fruit salad.

`W H a'
     Highlight the current article (`gnus-article-highlight').

`W H h'
     Highlight the headers (`gnus-article-highlight-headers').  The
     highlighting will be done according to the `gnus-header-face-alist'
     variable, which is a list where each element has the form (REGEXP
     NAME CONTENT).  REGEXP is a regular expression for matching the
     header, NAME is the face used for highlighting the header name and
     CONTENT is the face for highlighting the header value.  The first
     match made will be used.  Note that REGEXP shouldn't have `^'
     prepended--Gnus will add one.

`W H c'
     Highlight cited text (`gnus-article-highlight-citation').

     Some variables to customize the citation highlights:

    `gnus-cite-parse-max-size'
          If the article size if bigger than this variable (which is
          25000 by default), no citation highlighting will be performed.

    `gnus-cite-prefix-regexp'
          Regexp matching the longest possible citation prefix on a
          line.

    `gnus-cite-max-prefix'
          Maximum possible length for a citation prefix (default 20).

    `gnus-cite-face-list'
          List of faces used for highlighting citations.  When there
          are citations from multiple articles in the same message,
          Gnus will try to give each citation from each article its own
          face.  This should make it easier to see who wrote what.

    `gnus-supercite-regexp'
          Regexp matching normal Supercite attribution lines.

    `gnus-supercite-secondary-regexp'
          Regexp matching mangled Supercite attribution lines.

    `gnus-cite-minimum-match-count'
          Minimum number of identical prefixes we have to see before we
          believe that it's a citation.

    `gnus-cite-attribution-prefix'
          Regexp matching the beginning of an attribution line.

    `gnus-cite-attribution-suffix'
          Regexp matching the end of an attribution line.

    `gnus-cite-attribution-face'
          Face used for attribution lines.  It is merged with the face
          for the cited text belonging to the attribution.

`W H s'
     Highlight the signature (`gnus-article-highlight-signature').
     Everything after `gnus-signature-separator' in an article will be
     considered a signature and will be highlighted with
     `gnus-signature-face', which is `italic' by default.
