Subject: If a "?/" query produces an exact match for the string entered, but
 also produces non-exact matches, then the exact match is shown right away,
 but with a footer saying that you can press space to look at the list of
 non-exact matches.

When done with a "?/" query, the user is returned to the inital "/?"
prompt.
