It occurred to me that I should have drawn attention to the "with `mouse-1'
here. A user who never clicks a link with `mouse-1' is never asked the
question.

Only a user who naively expects `mouse-1' to follow a link will be informed
that standard Emacs behavior is to use `mouse-2' and asked to confirm that
s?he wants `mouse-1' to also follow links.
