You can use white-space:pre-wrap
on the tooltip. This will make the tooltip respect new lines. Lines will still wrap if they are longer than the default max-width of the container.
.tooltip-inner {
white-space:pre-wrap;
}

If you want to prevent text from wrapping, do the following instead.
.tooltip-inner {
white-space:pre;
max-width:none;
}

Neither of these will work with a
in the html, they must actually be actual newlines. Alternatively, you can use encoded newlines 
, but that's probably even less desirable than using <br>
's.
