    /*
     * Original Script 'Find and Navigate to Headers' by Tim Nahumck.
     *
     * Enhanced by Stefano F. Rausch:
     *
     * - Applied the modular pattern.
     * - Using the strict programming conventions.
     * 
     * - Better ( real ) header recognition.
     * - Empty headers will not appear in the list of jump points.
     * - Jump to the start or end of a draft even if headers are missing.
     * - Simplified the conditional statements user response-wise.
