Title: Contribution guideline: avoid false positives.

Suggestion: Contributions should avoid false positives.

It's easy to add a new language with a file extension in languages.yml, but that may result in a great number of files being misdetected. This isn't doing new languages any service, since e.g. searches, trendling lists, etc will be cluttered with unrelated results.
