If a wiki document contains headers and pre's (note spaces added below so it doesn't get formatted):

{{toc}}
  h1. Blah
  < pre >xxxx< /pre >
  h1. Boo

Then the TOC will be truncated. This is because application_helper calls parse_headings on each non-pre segment, which is incorrect it must call it on the entire document.

This broke in svn 4376:

Extract headings and TOC parsing from the textile formatter.
Fixes #2038 and #3707 and will allow to support TOC with other text formatters.
