report to ffmpeg developers. is either a bug or they changed the syntax.

Will do. Either way, it's a bug because the man page still mentions "copy".

Did you contact upstream about this issue?

This is not a bug. Placement of options is important. Anything before an "-i" is considered an input option, so ffmpeg is attempting to apply "-vcodec copy -acodec copy -scodec xsub" to the decoder of your input which is why you get the message, "Unknown decoder 'copy'". Move appropriate options before your output if you want them applied to the output.
