750 ** source of mutt's original manual.
752 ** - \fI switches to italics
753 ** - \fB switches to boldface
754 ** - \fP switches to normal display
755 ** - .dl on a line starts a definition list (name taken taken from HTML).
756 ** - .dt starts a term in a definition list.
757 ** - .dd starts a definition in a definition list.
758 ** - .de on a line finishes a definition list.
759 ** - .il on a line starts an itemzied list
760 ** - .dd starts an item in an itemized list
761 ** - .ie on a line finishes an itemized list
762 ** - .ts on a line starts a "tscreen" environment (name taken from SGML).
763 ** - .te on a line finishes this environment.
764 ** - .pp on a line starts a paragraph.
765 ** - \$word will be converted to a reference to word, where appropriate.

767 ** - '. ' in the beginning of a line expands to two space characters.
