bug#14795: height parameter inconsistent in new vs existing frames when tool-bar is enabled |

Package: emacs
This happens since at least 22.1, and I think has been discussed
before on emacs-devel, but I've been unable to find the reference.
emacs -Q
(let ((params '((height . 25))))
(make-frame params) ;; f1
(modify-frame-parameters (make-frame) params)) ;; f2
f1 = 28 lines
f2 = 25 lines
Adding (tool-bar-lines . 0) to params, both frames are 25 lines.
Obviously, when creating the frame Emacs is allowing three additional
lines as space for the toolbar. tool-bar-mode defaults to 3 in a newly
created frame, at least once it has been displayed:
(let ((f (make-frame)))
(cons (frame-parameter f 'tool-bar-lines)
(progn
(sit-for 0)
(frame-parameter f 'tool-bar-lines))))
=> (1 . 3)
Does that happen in all platforms? If so, shouldn't we make the
meaning of the height frame parameter consistent in all its uses?
