michael@0:  *  Description:        Based on ECMA 2 Draft 7 February 1999
michael@0:  *  Simple test cases for matching OctalEscapeSequences.

michael@0:  *
michael@0:  *  WHY:  the original test expected the regexp /.\011/
michael@0:  *        to match 'a' + String.fromCharCode(0) + '11'
michael@0:  *
michael@0:  *  This is incorrect: the string is a 4-character string consisting of
michael@0:  *  the characters <'a'>, <nul>, <'1'>, <'1'>. By contrast, the \011 in the
michael@0:  *  regexp should be parsed as a single token: it is the octal escape sequence
michael@0:  *  for the horizontal tab character '\t' === '\u0009' === '\x09' === '\011'.
michael@0:  *
michael@0:  *  So the regexp consists of 2 characters: <any-character>, <'\t'>.
michael@0:  *  There is no match between the regexp and the string.
michael@0:  *
michael@0:  *  See the testcase ecma_3/RegExp/octal-002.js for an elaboration.
