Subject: vim-patch:8.2.4247: stack corruption when looking for spell
 suggestions

Problem:    Stack corruption when looking for spell suggestions.
Solution:   Prevent the depth increased too much.  Add a five second time
            limit to finding suggestions.
https://github.com/vim/vim/commit/06f15416bb8d5636200a10776f1752c4d6e49f31

Cherry-pick parentheses from patch 8.2.4402.
