Re: [PATCH] Fix `window-at' and `coordinates-in-window-p'

[Richard Stallman]

    I think it's easier to adjust the pixel coordinates right inside
    coordinates_in_window_p, which both functions use:

This is not clean, because it gives the arguments of
coordinates_in_window_p a peculiar meaning (and doesn't document it,
by the way).  It is much better to keep their meanings consistent
with the rest of Emacs.

I will fix the other call.

Meanwhile, I fixed the other reported bug in coordinates-in-window-p.
