Hi,
Doc string of `window-line-height' says:
Return nil if window display is not up-to-date. In that case, use
`pos-visible-in-window-p' to obtain the information.
However, using `pos-visible-in-window-p' seems ineffectual.
In fact, the following expression often returns nil:
(progn (pos-visible-in-window-p)
(window-line-height))
So I use `redisplay' instead of `pos-visible-in-window-p' as:
(or (window-line-height)
(and (redisplay t)
(window-line-height)))
and it correctly works.
Please correct the doc string.
