From 84963956535e9eff38b0d7638ce751039eb44bc2 Mon Sep 17 00:00:00 2001 From: Juri Linkov Date: Wed, 22 Mar 2023 09:44:02 +0200 Subject: [PATCH] * lisp/outline.el (outline--fix-buttons-after-change): Add save-match-data. It's important for a hook in after-change-functions not to change match-data. Otherwise it breaks functions that make changes in the buffer, such as for example, successive calls to delete-region in smerge-keep-n, etc. --- lisp/outline.el | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lisp/outline.el b/lisp/outline.el index a89985d1990..0e90c59c285 100644 --- a/lisp/outline.el +++ b/lisp/outline.el @@ -1877,7 +1877,7 @@ With a prefix argument, show headings up to that LEVEL."
