I think I've found one limitation with this.

Often a target will be using a common set of resources to implement all 
the different watchpoint/breakpoint types.

With that in mind, I'd like to propose a slight extension:

@code{Z?}@code{,}@var{type}@code{,}@var{count}@{@code{;} 
@var{type}@code{,}@var{count}@}

i.e.,

	Z?,1,4;3,5

It sends down a count for each watchpoint/breakpoint type.  This will 
need a tweak to the internal interface.

Thoughts?
