/**
* File Name: RegExp/octal-003.js
* ECMA Section: 15.7.1
* Description: Based on ECMA 2 Draft 7 February 1999
* Simple test cases for matching OctalEscapeSequences.
* Author: christine@netscape.com
* Date: 19 February 1999
*
* Revised: 02 August 2002
* Author: pschwartau@netscape.com
*
* WHY: the original test expected the regexp /.\011/
* to match 'a' + String.fromCharCode(0) + '11'
*
* This is incorrect: the string is a 4-character string consisting of
* the characters <'a'>, <nul>, <'1'>, <'1'>. By contrast, the \011 in the
* regexp should be parsed as a single token: it is the octal escape sequence
* for the horizontal tab character '\t' === '\u0009' === '\x09' === '\011'.
*
* So the regexp consists of 2 characters: <any-character>, <'\t'>.
* There is no match between the regexp and the string.
*
* See the testcase ecma_3/RegExp/octal-002.js for an elaboration.
