LilyPond Contributor's Guide: 5.4.5 Text formatting

### 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. ‘makeinfo’ 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`.
