After a hearty round of confusion on my part, I'm not longer certain
I'm running code different from what you're running; I'm at least not
running code that is substantively different.

I got tripped up on a pretty silly thing:

you print the final '</svg>' line and end the line with a '\r'.  When
I go to cat this file, my terminal will not display the final line,
as it is doing line buffering and we haven't used '\r' to be the end
of line since very dark days.  If I instead say:

  $ cat empty.svg && echo

I do get that final line, that final echo triggers my line buffering
to flush the final line.  It turns out that I uncovered an interesting
problem working on this:

  https://bugs.call-cc.org/ticket/721

But one that has nothing to do with SWIS or the generated .svg
files.  It has to do with interactive line-editing in a very
unrelated program.  I will ask, however:

Will you use a proper line-ending in your final line, either a "\n"
or a "\r\n"?  Ending it with a single "\r" caused me a lot of
confusion today.
