5.4.5 Text formatting

• Lines should be less than 72 characters long. (We personally recommend writing with 66-char lines, but do not bother modifying existing material). Also see the recommendations for fixed-width fonts in the Syntax survey.
• Do not use tabs.
• Do not use spaces at the beginning of a line (except in @example or @verbatim environments), and do not use more than a single space between words. ‘texi2any’ copies the input lines verbatim without removing those spaces.
• Use two spaces after a period.
• In examples of syntax, use @var{musicexpr} for a music expression.
• Don’t use @rinternals{} in the main text. If you’re tempted to do so, you’re probably getting too close to “talking through the code”. If you really want to refer to a context, use @code{} in the main text and @rinternals{} in the @morerefs.
