引用符をつけてコピーするuserChrome.uc.js CopyRef

引用符ってのは例えば

ハロー、
ワールド

こんな文章をコピーしたとき

>ハロー、
>ワールド

こんな風にしてくれる機能
いままではCopyURL改造して使ってたんだけどfxのバージョンアップの度に改造するのが面倒になったのでuserChrome.js使うようにしてみた。

• http://www.code-404.net/article/2007/07/15/copy-url-lite
• 軽量マウスジェスチャー用をどーぞ
• CopyURL

あたりを参考にした。
土台はcopy-url-liteで元を生かすように改造した（と言うかほとんどパクった）ので共存するように改造するのもたやすいはず。
（はてなダイアリはテキスト添付できないのか。面倒だな）

空白の引用符ってなにに使うの？といわれそうw
pukiwikiのpre引用がこの形だったのです。
