If dfaexec() runs in non-UTF8 locales, length and wide character
representation are checked for all characters of a line in a input
string. However, if matched early in the line, results for remaining
characters are wasted.
This patch checks multibyte characters on demand. It enables to
accomplish to speed-up for matched early and reduce required memories.
