Remove operator-linebreak override for '='
Remove operator-linebreak override for '='

Airbnb style does not allow line breaks around '=' instead requiring
parentheses around unbreakable assignments.  This takes up an extra line
and adds visual clutter.  I don't see the advantage.  Override
operator-linebreak to remove the restriction.
