ASDF does this, but uiop/contrib/debug.lisp is not loaded by ASDF. It's
loaded by invoking LOAD:

(defun debug-lisp ()
  (make-sub-pathname :directory '(:relative "contrib") :name "debug"
:type "lisp" :defaults *uiop-directory*))

....

(load (debug-lisp))

So it's not a problem of ASDF or of me doing something wrong, it's
because LOAD is just doing whatever it normally does (presumably getting
the information from my US_en locale...).

I don't expect to live long enough to figure out how to fix this for all
implementations' versions of LOAD (since external-formats are, alas,
implementation dependent in the spec), nor does it seem like a
profitable use of our time, so let's drop it.

I suppose the alternative would be to use ASDF to load debug, instead of
using a bespoke pathname...
