Properlay clean the global RM variable if cgetstr() failed for it.
Otherwise, a connection attempt to a remote machine was made (and a
bogus result code printed) if a local printer followed a remote one in
printcap, and you did a `lpq -a', since checkremote() falsely assumed
the printer to be a remote one.
While i was at it, removed a gratuituous newline printed in front of
the remote machine's name, thus making the output more consistent (and
better machine-parseable) now.
