Looking at the patch, it would not produce the desirable result for

amenity=restaurant, cuisine=pizza;kebab

With my restaurant-cuisine.patch, this would create two entries for
such restaurants.  (I've since revised my patch to say cuisine=pizza*
so that pizza;kebab places will end up in the pizza restaurants
menu instead of "other restaurants".)

I think that the splitting of the node should be made explicit in the
style file.  Then, some special cases could still be handled differently.
Something like this:

amenity=fuel;shop [ 0x2e06 resolution 19 ]
amenity=fuel;* { split amenity=fuel, amenity=+5 }

The syntax is just a suggestion.  The latter rule would discard the original
node and create two new nodes: one with amenity=fuel, and the other with
amenity=... (whatever follows the fuel; in the original string).  The latter
rule wouldn't match already processed nodes, such as amenity=fuel;shop.
All rules would then be processed for each node again.  What do you think?
