Please re-read what I wrote. GIMP uses the file contents to discover
*which* image it's dealing with, but it's not using it to discover whether
it's an image or not. It's quite different: I believe there is pretty much
no known overlap between the various image formats used today, so you can
decide which image format it is unambiguously based on the contents. But in
Emacs if we use content-based detection we have to be ready to deal with an
ambiguity with any other file format, that a whole other ball game.
