Rather than introduce yet another user variable for setting the mode 
automagically, why don't we get rid of magic-mode-alist and build that 
functionality into auto-mode-alist instead.

Then the user can set the relative precedence of magic and glob patterns 
to their hearts content, and if they look at auto-mode-alist, it is 
clear what order the rules will be applied in.

For example we could use a list in place of regexp to mean an extended 
method of determining file type, with the car of the list indicating the 
method to be used:

(add-to-list 'auto-mode-alist '((magic "<\\?xml ") . xml-mode))
