multi lines in button_to

I am using
ROR 2.2.2.

In order to make my layout look a bit better I would like to put two
words on a button label and have them on two lines. I tried to put a
break in the label text but it just ended up as escaped html. Is there
any way to put in multi-lines other than writing my own button_to
helper? I couldn’t find any help in the documentation or on google.

Thanks

Norm
