the third arguments.

sql/opt_range.cc:
  Fixed bug #18165.
  Made [NOT]BETWEEN predicates SARGable in respect to the second and 
  the third arguments.
  Put in a separate function called get_full_func_mm_tree the functionality
  that builds a conjunction of all SEL_TREEs for a simple predicate of the
  form (f op c), where f was a field and c was a constant, applying different
  equalities f=f' with f' being another field.
