"SEO Experts" talk about a lot of stuff. There is a lot of snake oil ideas sold by "SEO Experts".
You think googlebot or any important search index bot doesn't read a title if it wraps a line?
Sorry, I don't think that and have more important things to work on. Furthermore changing that would be something that could break sites on the next upgrade since title is in the layout.master of the skin.
This is not a bug.
