It's just the way the map style sheet has been written. The cities are
set to never wrap. For towns the name will wrap if the caption gets
larger than 20 pixels.
I don't know the reason behind this styling.

You can see the stylesheet here if you want:
http://trac.openstreetmap.org/browser/applications/rendering/mapnik/osm.xml
search for the [place] = 'city' part. The wrap_width variable controls
whether multiple lines are used.

There's no way to actually force a line break though.
