This patch improves performance for input string which doesn't match
even the first part of a pattern. Although there is no less effective
for grep as it uses a superset of DFA, gawk speeds up about 40%.
$ time -p env LC_ALL=ja_JP.eucJP ./gawk '/k/ { print }' ../k
(before)
real 2.85 user 2.79 sys 0.05
(after)
real 1.70 user 1.64 sys 0.06
I think that this improvement should have been performed in bug#17576.
