OK, I think there is a misunderstanding about what is causing the
message.  I don't think it is any

  set term png font helvetica

command.  Octave doesn't send that.  It sends

  set terminal png enhanced;

The problem is the

  set xlabel "x" textcolor rgb "#000000" font "helvetica,10" rotate by 0.000000;

command that Octave sends.

So it seems to me that it is still a bug in gnuplot that it can
(apparently) figure out that helvetica is missing and fall back on a
default font when the font is specified in the "set term" command but
not when it is specified as part of a "set xlabel" command.
