tree that I wasn't quite ready for. It may as well stay in now though.
In order.
1. Pull out the code that deals with <segmentedlist>, the regular
stylesheets handle that now.
2. Change how $email-footer$ is handled. This requires changes to the
<lang>/share/sgml/freebsd.dsl files, to come very shortly.
3. Redo warning and caution label support. This is no-op, as Norm's
sheets don't support this the way I want yet.
4. Remove a useless comment.
5. Pull out the experimental docinfo stuff, it doesn't work.
6. Pull out the special handling of <literallayout>, the regular
stylesheets handle that now too.
