0.9.5.13:
        Some test framework improvements, inspired by trying to remote-debug a
        test failure on #lisp:

        * Print a backtrace for unhandled errors (unless running with
          --break-on-failure).
        * Consistently use HANDLER-BIND instead of HANDLER-CASE, to
          get the backtrace/debugger prompt in the right dynamic
          state.
        * Name all WITH-TESTs. Most tests were already named, and the
          automatically assigned numbers aren't really optimal for
          locating tests.
