Andrew, were you suggesting something like this?

from
   output ==> ( out-of-band-record )* [ result-record ] "(gdb)" nl
to
   output ==> (out-of-band-record nl)* [ result-record nl] "(gdb)" nl

and removing the 'nl' everywhere else?

That might actually work. Although, I don't personally know a way of
changing a grammar and guaranteeing that there the same.
