Make the quick cd behavior trigger even if the user was starting to type a token and even if the path is not a directory. Before, it would only prepend ./ if the command line was empty and the selected path is a directory.

Now, if the user was in the middle of inputting the first token and only one path is selected, then prepend ./ to the selected path so that
 - if the path is an executable, the user can hit Enter one more time to immediately execute it
 - if the path is a directory, the user can hit Enter one more time to immediately cd into it
