  42  * SUMMARY: '\400' should lex as a 2-digit octal escape + '0'
  43  * See http://bugzilla.mozilla.org/show_bug.cgi?id=177314
  44  *
  45  * Bug was that Rhino interpreted '\400' as a 3-digit octal escape. As such
  46  * it is invalid, since octal escapes may only run from '\0' to '\377'. But
  47  * the lexer should interpret this as '\40' + '0' instead, and throw no error.
