Subject: patch 9.2.0413: Scrolling wrong with 'splitkeep' when changing 'cmdheight'
X-Git-Tag: v9.2.0413^0
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=bd0f3e6da5df70ab2250264d0a7efc7db83c3dc8;p=thirdparty%2Fvim.git

patch 9.2.0413: Scrolling wrong with 'splitkeep' when changing 'cmdheight'

Problem:  Cursor is not adjusted when 'cmdheight' is changed to cover
          the cursor with 'splitkeep' ~= "cursor".
Solution: Handle window resize for 'splitkeep' after changing 'cmdheight'.
          Ensure previous window height is set when changing 'splitkeep'
          (Luuk van Baal).

closes: #20043
