/* Determine a suitable suffix
** ---------------------------

** given in the anchor.
**
** Returns a pointer to a suitable suffix string that must be freed
** by the caller. If more than one suffix is found they are all
** concatenated using the first delimiter in HTDelimiters.
** If no suffix is found, NULL is returned.
