patch 8.2.4082: check for autoload file name and prefix fails Commit: https://github.com/vim/vim/commit/3049fcf0a189b0fea8468fa308887b8252d93dce Author: Bram Moolenaar <Bram@vim.org> Date: Thu Jan 13 19:25:50 2022 +0000 patch 8.2.4082: check for autoload file name and prefix fails Problem: Check for autoload file name and prefix fails. (Christian J. Robinson) Solution: Only lower case the prefix on systems where the file name is not case sensitive.
