[luatex] description of node.traverse_{char,glyph}

[Hironori KITAGAWA]

Hello,

In LuaTeX Reference Manual, node.traverse_{char,glyph} are described as
>  <node> n, font, char = node.traverse_char(<node> n)
>  <node> n, font, char = node.traverse_glyph(<node> n)

But this differs from the actual behavior:

% test-traverse.tex
abc
\directlua{
   for n,f,c in node.traverse_glyph(tex.nest[tex.nest.ptr].head) do
     texio.write_nl('term and log', 'f=' .. tostring(f) .. ', c='
       .. tostring(c))
   end
}
\bye

$ luatex test-traverse.tex
