Of course there's something won by returning the exact, non-stripped
string when the user has selected one of the choices.  It tells us
exactly that -- that the user has chosen between one of the (textually)
identical versions.

In imdb-mode, if the user has selected a film, it displays that directly.
If the user types in a film name without making a selection, it pops up
a new buffer and asks the user to choose between the alternatives.
