If we rename tutor.zh.utf-8 to tutor.zh_tw.utf-8, then we need to have a
fallback for when s:lang is not defined. Using the zh_cn one is the
best guess, so this should work:

if s:ext =~? '\.zh'
if &enc =~ 'big5\|cp950'
let s:ext = ".zh.big5"
elseif &enc != 'utf-8'
let s:ext = ".zh.euc"
elseif exists("s:lang") && s:lang =~? 'zh_tw'
let s:ext = ".zh_tw"
else
let s:ext = ".zh_cn"
endif
endif
