Steel Bank Common Lisp

First off, apologies if this has been answered
before.  I cannot see a way to search the
sbcl-help archives today.  :(

I am having trouble finding valid symlinks
with #'DIRECTORY.  Maybe some of this is
still confusion on my part about the difference
between pathnames, pathname designators,
and pathspecs.  Anyhow, here's what I have:

-----------------------------------------------------------------
% touch a     # make a file called a
% ln a b      # make b refer to same file as a
% ln -s a c   # make c a symbolic referal to a
% ln -s e d   # make e a symbolic link to non-existent file

% ls -li
2608982 -rw-r--r--  2 pat  staff  0 Mar  2 15:56 a
2608982 -rw-r--r--  2 pat  staff  0 Mar  2 15:56 b
2608985 lrwxr-xr-x  1 pat  staff  1 Mar  2 15:56 c -> a
2608986 lrwxr-xr-x  1 pat  staff  1 Mar  2 15:56 d -> e

% sbcl
* (directory #P"./*.*")
(#P"/Users/pat/tmp/foo/a"
    #P"/Users/pat/tmp/foo/b"
    #P"/Users/pat/tmp/foo/d")
-----------------------------------------------------------------

So, DIRECTORY returns me the names of symlinks
that don't really point to files, but skips those that do.
Is this intended behavior?  Do I have to switch to
(sb-posix:opendir) if I want to see "c" also?

Thanks,
Patrick
