Original GitHub issue: https://github.com/DavidAnson/markdownlint/issues/120

Why the rule MD040 is introduced?

Why not using "code block" without syntax highlighting?
It is a simple useful marking for a preformatted text without indenting.

@DavidAnson commented on GitHub (May 8, 2018):

Correct syntax highlighting is usually clearer for the reader than without it, so this rule helps remind authors to add a language. If you do not want to do that, the rule can be disabled OR 4-space indenting can be used to create the code block instead.

I always specify a language when there is one, but not sure what to specify when there is no corresponding language? For example, log output or help messages? Is there a language that can be specified which means no-syntax-highlighting?

@dhimmel, Usually “text” doesn’t do any highlighting.
