vim-patch:9.1.1612: Ctrl-G/Ctrl-T do not ignore the end search delimiter

Browse Source 
Problem:  Ctrl-G/Ctrl-T does not ignore the end search delimiter
          (irisjae)
Solution: Check if the pattern ends with a search delimiter and ignore
          it, unless it is part of the pattern.

fixes: vim/vim#17895
closes: vim/vim#17933
