Hi Carl, thanks for the review.  I think I have fixed this, and all of the other formatting issues mentioned, with the attached patch.  I ran tools/patcheck and I got some messages about "egrep: empty (sub)expression", maybe because I'm running it on Mac OSX, but it no longer complains about whitespace or bracket issues.

The codec needs to exist so it can be opened, even if you never call decode/encode on a packet.  Maybe the decoder is not needed when using -codec copy?  But it seems the encoder is, otherwise avcodec_find_encoder(AV_CODEC_ID_EIA_608) returns NULL.  I could omit the decoder if that is better (can always add it as a separate patch if needed).
