So "" is assumed to mean "don't update"?  My assumption was that "" meant
empty description.

It seems silly to make someone replace the description with a space (or
something like that) if they truly want to zero it out.  And it seems silly
to ever make your description be "null".  So it seemed natural to make null
and/or undefined be such a signal.
