Ignoring pdftex primitives

But that surely is the point, at least with the primitive syntax
you might have a clue why depthcharge.png fails, but how is the serious
latex user supposed to know why \includegraphics{depthcharge} fails.
So, since I think you have write control for pdftex.def these days,
better release a copy that has \noexpand\noexpand\noexpand\@empty
before the #1 in all cases where pdftex uses \pdfimage :-)

I agree that a better primitive syntax would be nice, but making latex
work with the current synatax does not do any harm.
