[Armedbear-devel] wild-pathname-p inconsistent?

[Pascal J. Bourguignon]

Why do we have?

    (wild-pathname-p  #P"*-blah") -> T
    (wild-pathname-p  #P"*-blah" :name) -> NIL

This is inconsistent (and non-conforming). 
Actually wild-pathname-p returns NIL for all fields:

(mapcar (lambda (field) (wild-pathname-p  #P"*-blah" field))
        (list :host :device :directory :name :type :version))'
--> (NIL NIL NIL NIL NIL NIL)

If that was true, then (wild-pathname-p #P"*-blah" nil) should return
NIL, not true.


    If field-key is not supplied or nil, wild-pathname-p returns true if
    pathname has any wildcard components, nil if pathname has none. If
    field-key is non-nil, wild-pathname-p returns true if the indicated
    component of pathname is a wildcard, nil if the component is not a
    wildcard.

So we should have:

   (defun wild-pathname-p (path &optional field-key)
     (if (null field-key)
         (some (lambda (field-key)
                 (wild-pathname-p path field-key))
               '(:host :device :directory :name :type :version))
         …))
