bug#41737: 26.3; (window-text-pixel-size) in console

[Tomas Hlavaty <tom@logand.com>]

Hi,

(window-text-pixel-size) in console seems to be wrong.

The width seems to the width of the (visible) window.

The height seems to be number of lines in a file.  However, when
evaluated in notmuch thread, the cdr of the return value is a number
which I cannot interpret (it is not number of lines in the buffer and it
is now height of the visible window).

   Return the size of the text of WINDOW’s buffer in pixels.  WINDOW
   must be a live window and defaults to the selected one.  The return
   value is a cons of the maximum pixel-width of any text line and the
   maximum pixel-height of all text lines.

I suppose that pixel in console is one character.

   the maximum pixel-width of any text line

but this does not seem to be true.  I have file with long line but it
still returns number of visible columns.

   maximum pixel-height of all text lines

It is not clean, what does that mean and the returned number doesn't
seem to be useful for anything.

Thanks,

Tomas
