"Highlight message headers between start and end.
Faces used:
wl-highlight-message-headers the part before the colon
wl-highlight-message-header-contents the part after the colon
wl-highlight-message-important-header-contents contents of \"important\"
headers
wl-highlight-message-important-header-contents2 contents of \"important\"
headers
wl-highlight-message-unimportant-header-contents contents of unimportant
headers
wl-highlight-message-cited-text-N quoted text from other
messages
wl-highlight-message-citation-header header of quoted texts
wl-highlight-message-signature signature
Variables used:
wl-highlight-message-header-alist alist of header regexp with
face for header contents
wl-highlight-citation-prefix-regexp matches lines of quoted text
wl-highlight-force-citation-header-regexp matches headers for quoted text
wl-highlight-citation-header-regexp matches headers for quoted text
If HACK-SIG is true,then we search backward from END for something that
looks like the beginning of a signature block, and don't consider that a
part of the message (this is because signatures are often incorrectly
interpreted as cited text.)"
