I could reproduce the bug.

In my last kewords definition, underscores in a function name was not handled.
Now underscores and periods are handled.

I've changed my mind: the addresses have no fontification becuase finally I 
think 
too decorative.

The address fontification will be worth if other gud-ui buffers
introduce font-lock; the awareness of address string in the buffers
will be improved by using the same face on the all gud-ui buffers.
However, I have not used other buffers of gud-ui well yet, I should
not touch more. Switch view between source and machine code by
keyboard is much more important:)
