/*
*
* Date: 31 July 2002
* SUMMARY: Testing regexps containing octal escape sequences
* This is an elaboration of mozilla/js/tests/ecma_2/RegExp/octal-003.js
*
* See http://bugzilla.mozilla.org/show_bug.cgi?id=141078
* for a reference on octal escape sequences in regexps.
*
* NOTE:
* We will use the identities '\011' === '\u0009' === '\x09' === '\t'
*
* The first is an octal escape sequence (\(0-3)OO; O an octal digit).
* See ECMA-262 Edition 2, Section 7.7.4 "String Literals". These were
* dropped in Edition 3 but we support them for backward compatibility.
*
* The second is a Unicode escape sequence (\uHHHH; H a hex digit).
* Since octal 11 = hex 9, the two escapes define the same character.
*
* The third is a hex escape sequence (\xHH; H a hex digit).
* Since hex 09 = hex 0009, this defines the same character.
*
* The fourth is the familiar escape sequence for a horizontal tab,
* defined in the ECMA spec as having Unicode value \u0009.
