As the following code and transcript demonstrate, translate-logical-pathname appears to be downcasing paths inconsistently:

;;; test.cl (setf (logical-pathname-translations "foo") '(("foo:bar;*.lisp" "/FooRoot/bar/*.lisp") ("foo:*.lisp" "/FooRoot/*.lisp")))

;;; In the following pathname translation, the entire path is downcased (pprint (translate-logical-pathname "foo:bar;foobar.lisp")) ;;; In each of the next two, the entire path EXCEPT for the host is downcased -- ;;; the host is unchanged (pprint (translate-logical-pathname "foo:foobar.lisp")) (pprint (translate-logical-pathname "foo:Foobar.lisp"))

SBCL and CLISP both produce the following output for the above code:

#P"/FooRoot/bar/foobar.lisp" #P"/FooRoot/foobar.lisp" #P"/FooRoot/foobar.lisp"

Allegro's ALISP and MLISP both produce the following:

#P"/FooRoot/bar/foobar.lisp" #P"/FooRoot/foobar.lisp" #P"/FooRoot/Foobar.lisp"
