Patch.
The changes in DateTools may affect users with very strange default locales
that indexed with prior Lucene versions, but this is unlikely a problem, as the
whole sorting may be broken already.
Should I add a note to CHANGES.txt?

> This is a followup to LUCENE-1836: I found some more Locale problems in
> Lucene with Date Formats. Even for simple date formats only consisting of
> numbers (like ISO dates), you should always give the US locale. Because the
> dates in DateTools should sort according to String.compare(), it is
> important, that the decimal digits are western ones. In some strange locales,
> this may be different. Whenever you want to format dates for internal formats
> you exspect to behave somehow, you should at least set the locale to US,
> which uses ASCII. Dates entered by users and displayed to users, should be
> formatted according to the default or a custom specified locale.
> I also looked for DecimalFormat (especially used for padding numbers), but
> found no problems.
