runtime(vim): Improve Vim9 and legacy-script comment highlighting (#13104) Commit: https://github.com/vim/vim/commit/04e5363b823827f144409df011376d00ea6df750 Author: dkearns <dougkearns@gmail.com> Date: Thu Apr 11 06:18:37 2024 +1000 runtime(vim): Improve Vim9 and legacy-script comment highlighting (https://github.com/vim/vim/issues/13104) This is a first-pass attempt to limit matching of Vim9 and legacy-script comments to the appropriate syntactic contexts. Vim9-script comments are highlighted at top level in a Vim9-script file, in all :def functions, and in all :autocmd and :commmand command blocks. Legacy-script comments are highlighted at top level in a legacy script file, in all :func functions and in the Vim9-script preamble before the :vim9script marker command. Fixes #13047, #11307 and #9587. Signed-off-by: Doug Kearns <dougkearns@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
