Allow matching items exactly instead of fuzzily when prefixing the search with ' (like in fzf) or with --script-opt=console-exact_match=yes. This is mainly useful to filter history entries chronologically. You can also specify multiple search terms delimited by spaces. But ' makes every term an exact match, unlike fzf where you need to place it before every word, since we can't hook into fzy's algorithm. Closes #14587.
