Looking at the changset, now I remember:  That line was part of a change set
that was improving the *C* pretty-printer I added earlier and to
maximize  sharing
more cose between the C and C++ pretty printers.  The zero length was added
as an attempt to respect the *C* front-end desire not have line wrapping.
Richard talked about other front-ends, but at the time, there was only
two front-ends
who were using the pretty printers: C and C++.  The C front-end was adopting
bits of the C++ front-end.  Every other front-end were doing whatever
they wanted.
It wasn't like there was a bit debate with other front-ends to decide
what the default
should be for all.
