[Message part 3 (text/plain, inline)]

If a pattern includes an unsupported expression which is labeled as
BACKREF, a text will almost fail to match the pattern.

First patch makes changes to return immediately and avoid pidding search
if a pattern includes an unsupported expression.

Second patch removes word constraint support which is as labeled BEGWORD,
ENDWORD, LIMWORD and NOTLIMWORD for multibyte-locales including UTF-8
from DFA, as we use regex instead of DFA for a pattern including word
constraint so that it does not correctly treat word constraint.
