commit 2f316750cc7f9ed3b49349c2ca858a8d31e1ceb9
Author: Raymond Toy <toy.raymond at gmail.com>
Date:   Wed Oct 1 20:29:32 2014 -0700

    Fix regression in %ENUMERATE-DIRECTORIES.
    
    Previously (18a at least), %ENUMERATE-DIRECTORIES would return a path
    even if a directory element did not exist.  This behavior is restored.
    
    See email from cmucl-help, Sep 26, 2014.
    
     * src/code/filesys.lisp:
       * Fix regression.in %ENUMERATE-DIRECTORIES.  Even if the directory
         does not exist, we continue recursing instead of stopping.
     * src/general-info/release-20f.txt:
       * Update
     * tests/filesys.lisp:
       * New file adding tests for UNIX-NAMESTRING.
