`magic-mode-alist' is more specific. The problem is that some of these
regexps are too permissive. Supposing that anything that starts with
"#define " is a XBM file makes no sense.

I think it'd be good to apply the following patch, so auto-detection
of images by content is disabled, but available to these wanting to
set it up. (And we should mention `image-type-auto-detectable' in
NEWS.)
