>>> 1. Regexs with ^ or $ applied to copy empty strings caused infinite

>>> Applied a similar correction to that from version 1.1c, to
>>> #copyStream:to:(replacingMatchesWith:|translatingMatchesUsing:).
>>> 2. Extended RxParser testing to run each test for
>>> #copy:translatingMatchesUsing: as well as #search:.
>>> 3. Corrected #testSuite test that a dot does not match a null, which
>>> was passing by luck with Smalltalk code in a literal array.
>>> 4. Added test to end of test suite for fix 1 above.
>>>
>>> VERSION 1.2.2 (November 2006)

>>> There was no way to specify a backslash in a character set. Now [\\]
>>> is accepted.

>>> about matches when enumerating
>>> 3. Syntax description of dot corrected: matches anything but NUL
>>> since 1.1a
>>>
>>> VERSION 1.2 (May 2006)
>>>
>>> Fixed case-insensitive search for character sets.
>>>
>>> VERSION 1.1c (December 2004)

>>> loops
>>> for matches
>>> that matched empty strings.
>>>

>>>
>>> Changes valueNowOrOnUnwindDo: to ensure:, plus incorporates some
>>> earlier fixes.
>>>
