Shouldn't the signal have the c-name of emitting function if 
the signal is publically callable.  Having a signal
and the emit definitions separate means the relationship
is weak.  Since we prefer calls to be made to the emitting
function rather then directly with gtk_signal_emit, because
extra checking is done in the emit function.  

Defining them separately seems bad.  

(Okay, gtk-- is the place that makes the most use out of wrapping
the signals, and the c-function name is one of the primary requirements.
We consider signals to just be extensions of functions.)
