[tex4ht] tex4ht vs pgf

[Karl Berry]

    texmf-dist/tex/generic/pgf/systemlayer/pgfsys-tex4ht.def
    [...]
    \def\pgfsys at svg@newline{\Hnewline}

Peter, Victor (and all) - thanks for the debugging efforts.

This file is part of pgf, not part of tex4ht.  So it seems the bug
should be redirected to the pgf side.

If the pgf maintainers want/need some change in tex4ht, we can discuss.
(For what it's worth, \Hnewline is used all over tex4ht.)

Best,
Karl
