runtime(sh,zsh): clear $MANPAGER in ftplugin before shelling out Commit: https://github.com/vim/vim/commit/8d8cb45756cb7e6fda17013b8347be3a11b29610 Author: D. Ben Knoble <ben.knoble+github@gmail.com> Date: Mon May 6 19:52:53 2024 +0200 runtime(sh,zsh): clear $MANPAGER in ftplugin before shelling out Say you use Vim and set MANPAGER='vim -M +MANPAGER --not-a-term -'; then :{Zs,S}hKeywordPrg (or K) will crap out and spew terminal garbage into less when bash's "help" fails. This was introduced by 2f25e40b1 (runtime: configure keywordpg for some file types (#5566), 2023-08-23) and may be present in other files touched by that commit. Make the "man" invocation sensible by unsetting MANPAGER in the environment. Note that changing MANPAGER for `:terminal` is not needed; Vim within Vim is perfectly fine. closes: #14679 Signed-off-by: D.
