bug#14540: 24.3.50; Doc: pos-visible-in-window-p: ROWH

[Michael Heerdegen <michael_heerdegen@web.de>]

Hello,

in the docstring of `pos-visible-in-window-p', the explanation of ROWH
is not understandable (wrong, in my opinion).

It sounds like it would be the (complete) height of the row (visible +
non-visible part).  AFAICT, ROWH specifies the _visible_ height, as
mentioned in the manual (info "(elisp) Window Start and End").

I suggest to replace

[...]; otherwise, RTOP and RBOT are the number of pixels off-window at
the top and bottom of the row, ROWH is the height of the display row,
and VPOS is the row number (0-based) containing POS.

by something like:

[...]; otherwise, RTOP and RBOT are the number of pixels off-window at
the top and bottom of the display row at POSITION, ROWH is the visible
height of that row, and VPOS is the (0-based) row number.


Thanks!

Michael.
