[Vorbis] newlines in vorbis comments

[Ian Malone]

Is there any way to put a newline character in comments for ogg
vorbis files in Linux?  I can't see any way of doing it with
vorbiscomment.  Easytag would work, but has other problems
(like concatenating comment fields with the same tag name).

If I wanted to put together a quick hack to add a such a comment
(I'm thinking read the comment from a file, with the tag name
specified at the command line), what parts of the ogg/vorbis
documentation should I look at?
