I attach an early draft filemagic patch.

Some notes:

- The mime type info usualy is less granular than the free
text info:

file --mime /tmp/tst.xcf
/tmp/tst.xcf: application/octet-stream; charset=binary

file /tmp/tst.xcf
/tmp/tst.xcf: GIMP XCF image data, version 0, 640 x 480, RGB Color

This is dependent on the file magic info file used.

- We can probably have much fun debating what the interface should look
  like at the lisp level. Any ideas?
