 * SUMMARY: '\400' should lex as a 2-digit octal escape + '0'

 * See http://bugzilla.mozilla.org/show_bug.cgi?id=177314

 * Bug was that Rhino interpreted '\400' as a 3-digit octal escape. As such

 * it is invalid, since octal escapes may only run from '\0' to '\377'. But

 * the lexer should interpret this as '\40' + '0' instead, and throw no error.
