[R] I've forgotten, why is box("") the default?

[Simon Fear]

I've searched on CRAN for axes, axis, and other terms 
I've already forgotten, without (re)discovering the 
reason for S using "non-joining" axes by default, instead
of box("l").

MASS points me towards Cleveland (1993) but I don't 
have ready access to this any more. Could someone 
give me a one-liner to justify this choice to a sceptic?

It's something to do with not mis-interpreting the axes
intersection as (0,0), isn't it?

TIA,
Simon
