CMUCL 20b and SBCL 1.0.43

CMUCL 20b is out. Read the release notes. I'm glad a bug I reported was fixed:

    - DELETE-FILE, ENSURE-DIRECTORIES-EXIST, FILE-AUTHOR,
      FILE-WRITE-DATE, and OPEN now merge the given pathname with
      *DEFAULT-PATHNAME-DEFAULTS* as required by CLHS sec 19.2.3.

SBCL 1.0.43 is also out. Read the release notes. It has a ton of bug fixes and a few enhancements, too.
