All I found was the binding vi-eof-maybe, which I couldn't find any
documentation on, but if I set control-D to do it, it acts like enter
if text is on the line and like control D otherwise.  It's hard to
tell if this is what it's supposed to do or if IPython is just not
recognizing the EOF with other text.
