Sounds like excellent material. It is available under [1], just for the 
reference.
XDG would return XDG_MIME_TYPE_UNKNOWN if the fopen fails, and multiple 
MIME types specify identical matching glob patterns, right?

While this still wouldn't work for the more complex matches "README*", 
"*EAD*", "*DME", it takes care that container formats (ogg, avi) or glob 
patterns used by multiple mime TYPES "*.pot" friends play nicely with 
Nautilus. Since KDE AFAIK currently does the same (glob matching, 
contents for particular container MIME types only), it would also be 
useful for them.

It would be nice to get this in, and to get some feedback from potential 
XDG MIME API client projects. Are you willing to patch write a spec 
patch yourself, or should I tackle this?
