	* tool-bar.el (tool-bar-mode): Only change tool-bar-lines on
	graphical terminals.

change is inherently asymmetric with respect to future frames: Turning
`tool-bar-mode' off now adds an entry to `default-frame-alist' as before.
Turning it on now no more adds an entry.  IMHO, we should either not
call `modify-all-frames-parameters' in either case or call them in both
cases as in the (attached) tool-bar.el patch I proposed earlier.
