On a second thought, the +5 is a bad idea because of multi-byte characters
and character set conversions (e.g., latin1 is 1 or 2 bytes per character
in UTF-8 but 1 byte per charater in latin1).  Come to think of it, the *
on the right-hand-side could expand to what the * matched on the
left-hand-side:

amenity=fuel;* { split amenity=fuel, amenity=* }

This would also allow you to say

amenity=shop;*;fuel { split amenity=fuel;shop, amenity=* }
amenity=*;fuel { split amenity=fuel, amenity=* }

just to name crazy examples.

I don't think that it's necessary to have the split operator create more
than two nodes, but that could be done too.  For simplicity, I'd limit it
to one * on the left-hand-side, though.

(Sorry that I'm just throwing ideas and not writing any code.)
