patch 9.0.1957: termcap options should change when setting keyprotocol Commit: https://github.com/vim/vim/commit/3695d0e41ba26db074dd5680564a6f87d522fb61 Author: Gregory Anders <greg@gpanders.com> Date: Fri Sep 29 20:17:20 2023 +0200 patch 9.0.1957: termcap options should change when setting keyprotocol Problem: termcap options should change on keyprotocol setting Solution: Apply termcap entries when 'keyprotocol' changes When the 'keyprotocol' option was set after startup (including in a user's .vimrc) the termcap entries associated with the matching protocol were not applied. Thus, setting the option has no affect. When 'keyprotocol' is changed it should also update the termcap entries. closes: #13211 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Gregory Anders <greg@gpanders.com>
