	(redirect_handler): PROPFIND is defined to be "safe and
	idempotent", so allow automatic redirects of it. (Pointed out by
	Christian Kellner. FIXME: need a way for apps to declare
	additional safe methods). Also, treat 302 like 307, not like 303,
	because that behavior is universal in the real world, despite the
	spec's protests.

	* tests/redirect-test.c (tests): update POST 302 behavior check

	* tests/Makefile.am (TESTS): oops, add redirect-test so it gets
	run by "make check"/"make distcheck"
