Currently, a pin on the subschematic symbol is required for each 
connection to the actual subschematic.  However, if that really bugs you, 
something along the lines of

     connect-port-to=GNDPORT:GND

could be implemented.  That would still require an actual port in the 
subschematic, but you wouldn't see the respective pins on the symbol.

Assuming buses were already implemented in gEDA/gaf, how exactly would you 
expect to use them?
