bug#38223: grep >=2.28 cannot handle -wF correctly under LANG=ja_JP.eucjp

[Paul Eggert]

Thanks for fixing that. Although the patch says "[Bug#38223 introduced in grep 
3.0]", the original bug report is against grep 2.28 and later. Can I take it 
that we tried to fix the bug in 3.0 but the fix was incomplete?
