;;; Wrap the lines of a message with long lines so they're a little easier
;;; to read. Try to ignore what looks like preformatted text.
;;;
;;; A paragraph consisting only of short lines is not wrapped
;;; A paragraph with at least one line that starts with some odd
;;; character is not wrapped. Whitespace is considered odd if
;;; if occurs on any line but the first.
;;; A paragraph is not wrapped if it is more than one line long and the
;;; difference between line lengths is constant.
;;; Scan the text line by line, and decide whether to fill or not on a
;;; paragraph by paragraph basis.
;;;
;;; An empty line ends the current paragraph.
;;;
;;; An indented line followed by an unindented line ends the current
;;; paragraph and starts a new one. An indented line followed by the
;;; end of the buffer is also considered a paragraph if we have
;;; started a new paragraph based on indentation at least once before.
;;;
;;; An indented line followed by another line indented the same way
;;; starts a new paragraph if we're not already scanning a paragraph.
;;;
;;; Any text seen when not scanning a paragraph starts a new
;;; paragraph.
;;;
;;; When a paragraph is started, filling may be enabled or disabled or
;;; set in a "maybe" state.
;;;
;;; A line that does not look like it belongs to the current paragraph
;;; because it is inndented incorrectly or because it starts with a
;;; strange character disables filling for the entire paragraph.
;;;
;;; A line that is wider than the window enables filling for the
;;; paragraph, unless filling has been disabled earlier.
;;;
;;; Any line containing three whitespace characters in a row, a space
;;; followed by a tab, or a tab followed by a space, or two tabs in a
;;; row, or the beginning or end of a C comment or four hyphens
;;; disables filling for the entire paragraph.
;;;
;;; A paragraph is not filled if filling has been disabled, or if the
;;; difference in line lengths from paragraph to paragraph is
;;; constant.
