So people see less information on terminals that support hyperlinks,

I think there should be as much information displayed whether or not the
terminal supports hyperlinks.  Otherwise it can be confusing.
(Especially since we can’t tell whether the terminal really supports
hyperlinks: we don’t know whether it displays clickable links.)

I understand it’s a matter of taste, but I’m not a fan of the extra
line here.
