vim7.4で.shファイルを編集しようとしたらエラーが出た話

久しぶりにvagrant内にあるvimでhoge.shというファイルを編集しようとしたらエラーが出た。

"path/to/hoge.sh" 0L, 0C
Error detected while processing /usr/local/share/vim/vim74/syntax/sh.vim:
line  130:
W18: Invalid character in group name
Press ENTER or type command to continue

syntaxファイルがおかしいらしい。
vimのバージョンはこんな感じ

と言われているので、とりあえず見てみることに。

うーんなんだろう。
（この時の自分は見る気がなかったのだろう。
invalid character in group name vim shとぐぐると下記ページがヒット。

Vim Developer list

Yes, there seems to be an extra "t" on that line.

ん・・・？extra "t" ？？
おや、 @shCaseLis,t
Lis,t ・・・？タイポ・・・？ｗ
とりあえず、下記のように直しました。

syn cluster shLoopList  contains=@shCaseList,shErrorList,shCaseEsac,shConditional,shDblBrace,shExpr,shFor,shForPP,shIf,shOption,shSet,shTest,shTestOpr

動いた。なるほど。
