ISHIKAWA, Chiaki be2b50a7f8 Bug 1248252 - Improper outdated octal constant syntax in M-C tree. Use '0o' prefix. r=dao
Be warned. Do not attemp to change the .js "test" source code in ./js
They are meant to check

 - the outdated 0666 octal constant is still parsed correctly,
 - the outdated 0666 octal constant raises syntax error flag
   in strict mode, etc.

So leave them alone.
