Something like:

"Discard breakpoint, rather than mark it pending?"

is a guess.

The real problem here is with batch scripts, the change breaks existing 
script behavior (which is never a good thing).

How about this, we introduce:
	nquery()
	yquery()
where the default (batch mode, and when return is pressed is n/y 
respectively).  We'd need the language police to look over the interface 
but should otherwize be ok.

PS: There's a GUI bug here also.  The query doesn't contain the error 
message (cf my recent change to internal-error where I made certain each 
query contained the full context of the question).
