FYI: Add tests for PR36000 (region-based regex matching)

This adds a new test for the region-based pattern matching
I just implemented in java.util.regex.

It also makes the output more verbose for one of our existing
tests.  I needed this when debugging an issue with it a few
months back.

ChangeLog:

2008-05-12  Andrew John Hughes  <gnu_andrew@member.fsf.org>

	* gnu/testlet/java/text/SimpleDateFormat/regress.java:
	Make output more verbose.
	* gnu/testlet/java/util/regex/Regions.java:
	New test.
