* 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.
