From 35ce3fb141dd72f75408e71f2daba9b513ca89f2 Mon Sep 17 00:00:00 2001 From: Noam Postavsky Date: Sun, 4 Dec 2016 01:06:52 -0500 Subject: [PATCH] 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. --- lisp/emacs-lisp/cursor-sensor.el | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lisp/emacs-lisp/cursor-sensor.el b/lisp/emacs-lisp/cursor-sensor.el index 2231179de1c..28b61880d0a 100644 --- a/lisp/emacs-lisp/cursor-sensor.el +++ b/lisp/emacs-lisp/cursor-sensor.el @@ -114,7 +114,7 @@ ;; non-sticky on both ends, but that means get-pos-property might ;; never see it.
