bug#4543: window-full-height-p

`window-full-width-p' is based on the definition

  /* Total width of frame F, in columns (characters),
     including the width used by scroll bars if any.  */

  #define FRAME_TOTAL_COLS(f) ((f)->total_cols)

from frame.h whose semantics I don't understand.  Not really simple.

Hardly.  Also I suppose you don't want the return value include the
minibuffer height.  At least the comment in

    (if (not (= (1+ (window-height)) (frame-height))) ;not horizontally split

seems to suggest that (it confuses horizontally and vertically, BTW).
