Subject: [PATCH] patch 9.1.1107: cannot loop through completion menu with
 fuzzy

Problem:  cannot loop through completion menu with fuzzy and nosort in
          'completeopt'
          (Tomasz N)
Solution: Reset cur to zero and update compl_shown_match when
          'completeopt' contains "nosort" but not "noselect"
          (glepnir)

fixes: #16624
closes: #16629
