Don't assume window-point and point are the same
The function `cursor-sensor--detect' calls `bobp' to decide whether to
check properties at (1- (window-point)). However, (window-point) may be
at beginning of buffer, even if (point) is not. In this case an
`args-out-of-range' error will be signaled (Bug#25104).
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor--detect): Check the
value of (window-point) against (point-min), rather than (bobp) to
decide if (1- (window-point)) is accessible.
