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".
