/**
 *  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.
