Ping!

Referring to field 'command' instead 'cmd' works.  I could test for the
correct node field, but since node.has_field(n, 'cmd') returns true and
node.has_field(n, 'command') returns false with LuaTeX 0.76, one needed
to explicitly test for an error triggered by an assignment to either field.

\directlua{
  local WHATSIT = node.id('whatsit')
  local PDF_COLORSTACK = node.subtype('pdf_colorstack')

  local function test_node_cmd()
    local n = node.new(WHATSIT, PDF_COLORSTACK)
    n.cmd = 1
  end

  if pcall(test_node_cmd) then
    texio.write_nl('node.cmd')
  else
    texio.write_nl('node.command')
  end
}
\bye

Do I need to add such an ugly test to my code or may we expect this to
be fixed before TL2013 is released?
