Date index for Mar 2005

In a small informal organisation like ours, we like to work in Achievo
on a first-name basis. It would be nice and simple if a user could be
just "John" for instance. At the moment we're pretending the first
name is the last name, because that field is obligatory (which is
fine). Just one cosmetic bug: in the user pulldown this shows up as:

John,

It would be nice if the comma took a vacation when it's not necessary ;-)
