Subject: [PATCH] vim-patch:9.2.1040: matchfuzzypos() can be improved (#41786)

Problem:  matchfuzzypos() can be improved
Solution: Compute the uppercase character once per character in
          has_match(), instead of repeating the conversion while
          scanning each candidate (Yasuhiro Matsumoto).

closes: vim/vim#21241
