Subject: [PATCH] fix(vim-patch): :redrawtabpanel regexp, delay grep on hunk

Too many suggestions in
https://github.com/neovim/neovim/commit/bcf116cc2f2f59e6c0f5ce5a644f832476f77384

Multi-line grep on the hunk contents before filtering by hunk header
prevents vim-patch.sh from detecting v8.1.2195 and v8.1.2219 as N/A.

Revisit multi-line parsing for `runtime/doc/*.txt`
when Vim v9.2+ has new runtime/doc/ patches
about features that require "has()/exists()" guards.
