Removing word wrap. Setting max-width to 400px.

Per Github Styleguide (https://github.com/styleguide/css/9.0) on CSS: "The maximum width of the truncated text can be changed by overriding the max-width of the .css-truncate-target".

Instead of word-wrapping, I set the width to a (reasonable) amount. This indeed solves the problem, as described in issue #6.
