thanks

Sorry, I had missed Hilmar's point. Indeed --nogs isn't supposed to cause
reading from standard input; one can and should use --filter --nogs for that.

Retitling the bug since the only real problem is the failure to write to
standard output.

I've just successfully tested the attached patch. A side effect is that if
one does want to write to ./- one needs to say --outfile=./- rather than
--outfile=- ; but that's hopefully not a problem.
