Generally speaking, and that's not your fault, it would be nice to
have some documentation about this module in the GDB Users' Manual.
Would you be willing to help us in that department? - nothing fancy,
but something very basic that quickly lists all available option
and what they mean.  This can be treated as a separate patch.

In terms of the user interface for this change, why not just make
the size optional? So, either the user specifies "ADDR,SIZE", or
he says "ADDR".  That way, you do not need to treat zero as special.

I see, now, that this patch has already been checked in - I must have
missed the approval email.  But the suggestions are both still interesting,
IMO.
