[asdf-devel] contradiction in ASDF central-registry default vs code

[Faré]

The default for ASDF's *central-registry* in SBCL contains a
  (let (...) (when ...))
which can and *will* return NIL in some cases (i.e. when an executable
SBCL image is run).

On the other hand, sysdef-central-registry-search calls
directory-pathname-p on each entry, which assumes that
NIL is an invalid entry.

My proposed solution: directory-pathname-p should check that its
argument is indeed a pathname designator.
