??? Are you saying that posn-point would throw an error or otherwise
behave incorrectly if invoked on a tty without a mouse?  I tried that,
and it seemed to work fine for me.

I think whether a mouse is connected or not is not an issue, since a
click event object can be created manually even if there's no mouse.
And posn-at-x-y does precisely that, doesn't it?

I'm puzzled why did you need to patch xt-mouse.el, since these 2
functions seem to work for me on a tty, even a tty that lacks the
mouse.
