        leaf_to_root must be run multiple times is because we need to
        reject 'group' matches; for example the alternative form
        (a | b c) creates a group [b c] that needs to be matched. Since
        matching multiple linear patterns overcomes the automaton's
        capabilities, leaf_to_root merges each group into a single
        choice based on 'characteristic'ity,

        i.e. (a|b c) -> (a|b) if b more characteristic than c

        Returns: The most 'characteristic'(as defined by
          get_characteristic_subpattern) path for the compiled pattern
          tree.
