There are 140 people with the empty string as their displayname. I've reset
these displaynames, setting the field to the same as their name field. I
don't think it is possible to set names to the empty string any more via the
UI. I'm adding a constraint to Person.displayname ensuring that it can't be
the empty string or contain nothing but whitespace.

displayname is NOT NULL, and we need to ensure

There isn't much we an do about the remaining pathalogical cases where you
can create an invisible displayname (or nearly so) - its just a side effect
of using Unicode.
