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.

Internal function. Reduces a compiled pattern tree to an
intermediate representation suitable for feeding the
automaton. This also trims off any optional pattern elements(like
[a], a*).
