I think we should start by making things like

  {''}

and

  {char (zeros (2, 0))}

compatible.  I thought it would be simple to do this with the change
that I posted yesterday, but that caused other trouble.  I'm not yet
sure whether the fix I posted was the right thing to do (meaning that
the other bugs should be fixed) or whether compatibility should be
achieved by making a change at some other level (for example, in the
constructor that makes cell arrays from char matrices).
