From 4a8eb6e7a9df10f79bf95301ced012f0d6a13088 Mon Sep 17 00:00:00 2001 From: Christian Brabandt Date: Sun, 13 Aug 2023 19:43:42 +0200 Subject: patch 9.0.1710: scrolloff options work slightly different Problem: sidescrolloff and scrolloff options work slightly different than other global-local options Solution: Make it behave consistent for all global-local options It was noticed, that sidescrolloff and scrolloff options behave differently in comparison to other global-local window options like 'listchars' So make those two behave like other global-local options. Also add some extra documentation for a few special local-window options. Add a few tests to make sure all global-local window options behave similar closes: #12956 closes: #12643 Signed-off-by: Christian Brabandt --- runtime/doc/options.txt | 47 ++++++++++++++++++++++++++++++++++++----------- 1 file changed, 36 insertions(+), 11 deletions(-) (limited to 'runtime/doc/options.txt') diff --git a/runtime/doc/options.txt b/runtime/doc/options.txt index 9292b05a4d..ec2b8756bf 100644 --- a/runtime/doc/options.txt +++ b/runtime/doc/options.txt @@ -252,6 +252,8 @@ opt+=val" the expansion is done before the adding or removing.
