No match for all.

Before the patch:

$ locale -a | grep sjis
ja_JP.sjis
$ printf "\x82\x61\n" | env LC_ALL=ja_JP.sjis src/grep -i 'A'
dfaanalyze:
 0:A 1:a 2:OR 3:END 4:CAT
$ printf "\x82\x61\n" | env LC_ALL=ja_JP.sjis src/grep '[a]'
dfaanalyze:
 0:MBCSET 1:END 2:CAT

After the patch:

$ locale -a | grep sjis
ja_JP.sjis
$ printf "\x82\x61\n" | env LC_ALL=ja_JP.sjis src/grep -i 'A'
dfaanalyze:
 0:CSET 1:END 2:CAT
$ printf "\x82\x61\n" | env LC_ALL=ja_JP.sjis src/grep '[a]'
dfaanalyze:
 0:CSET 1:END 2:CAT
