0.9.4.6:
	Rewrite the test infrastructure to make it a bit more useful, without
        having to make major changes to the test files.

        Move most of run-tests.sh Lisp-side. New features:
        * Don't bail out at first failure (unless running with
          --break-on-failure)
        * Report failed tests at the end of the run
        * Tests can be marked as expected to fail on certain platforms
        * Tests can be named
        * A subset of test files to run can be specified on the command line

        Todo:
        * "Quis custodiet ipsos custodes?". Tests for the test framework.

        Changes to the tests:
        * Remove the explicit quits on success from the impure tests
          (handled by the test framework)
        * Mark some obvious cases as "expected to fail on FOO"

        Other:
        * Remove an (unrelated) fixed BUGS entry
