patch 8.2.4510: Vim9: shortening commands leads to confusing script Commit: https://github.com/vim/vim/commit/204852ae2adfdde10c656ca7f14e5b4207a69172 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Mar 5 12:56:44 2022 +0000 patch 8.2.4510: Vim9: shortening commands leads to confusing script Problem: Vim9: shortening commands leads to confusing script. Solution: In Vim9 script require at least ":cont" for ":continue", "const" instead of "cons", "break" instead of "brea", "catch" instead of "cat", "else" instead of "el" "elseif" instead of "elsei" "endfor" instead of "endfo" "endif" instead of "en" "endtry" instead of "endt", "finally" instead of "fina", "throw" instead of "th", "while" instead of "wh".
