This is where an OO like system (built on something like EIEIO with data
and methods) would be ideal.  If someone needs to specialize completion,
they just subclass, and override the bit they need.

Instead of calling a built-in core completion method, users would
subclass the core completion object, and then override the bits they
need to make a new completion engine.

This would be easier to design now than divining all future hook names
and finding a way to make a function call with an extensible number of
hook/action types.
