Fix eldoc-box-only-multi-line behavior

Browse Source 
Prior to this change, single line eldoc messages were just ignored
completely when eldoc-box-only-multi-line was non-nil, though they
should have been displayed in the minibuffer.

* eldoc-box.el (eldoc-box--enable): Change :before-until to :before-while.
(eldoc-box--eldoc-message-function): Return nil if the message is not
multi-line, so that the default eldoc message function picks up the
message.
