The Info frame already exists. It has no minibuffer, and it shows only
buffer *info*.

If I split the window in the frame then there is no problem, but
for the simple reason that no frame fitting is done (no call to
`set-frame-size').

I tried to give the (single-window) frame a minibuffer but was
unsuccessful. I tried both
M-: (set-frame-parameter nil 'minibuffer t) and
M-: (modify-frame-parameters nil '((minibuffer . t))).

Neither had any effect: the value of parameter `minibuffer' remained
nil.  (Am I missing something here?  Is that another bug?)
