How to configure nlinum to separate line numbers, buffer contents with a space?

[Andrew Pennebaker]

I recently discovered nlinum <http://elpa.gnu.org/packages/nlinum.html>, an
alternative to linum that doesn't choke when pasting huge blocks of text
into Emacs from other applications, yay!

Unfortunately, nlinum places line numbers right next to buffer contents,
which makes it harder to read any numbers in the buffer.

Does anyone know how to configure nlinum to separate line numbers and
buffer contents with a space?
