The thing at Livejournal where you can write posts in raw HTML has changed.
You turn on the box that says "disable autoformat", and it takes your stuff to be
HTML (as opposed to long-lined plaintext,
understands HTML, but now it inserts ＜br＞'s wherever you have a newline.
When I'm writing a paragraph of flowed HTML source, I don't want that, at all!
Apparently this all goes away if you start the message with
＜lj-raw＞ and have all your stuff, then end it with ＜/lj-raw＞
