My account was set to default to GUI mode, so the bug was triggered as soon as I opened the editor. It didn't occur to me until Dan denied knowledge of the existence of a GUI editor that I could change that. I did, and that does enable me to avoid the carriage return bug at the expense of not being able to see what the page will look like until it's saved.
Doesn't the "Preview" button work for you?
