Subject: - Switched the "short version" and the "long version" on the preview
 page.

- Removed a broken filter which caused some line breaks to be stripped.

- It is now possible to create short teasers and the '---' delimiter can
  be outside the allowed range but not more than a factor two.

- Fine-tuned teaser extraction in absence of the '---' delimiter.
