Sorry, what I wrote is wrong. To be more clear, it looks like ffmpeg itself does not require either the decoder or encoder to do -codec copy, but some of the other code I was testing did.
I attached a new patch that simply updates movenc.c to write the proper headers for this track. It still fixes ticket 846 and allows -codec copy to copy these tracks. I can re-submit the other changes as a separate patch later.
