I'm not sure I understand your meaning. My code doesn't have line breaks.

The code looks like this:

<String>A secretive people, little is known of Breen political or social structures. Even the climate of their homeworld remains a mystery to the other galactic powers. All Breen so far encountered wear special climate-controlled bio-suits, to facilitate interaction in alien environments. The Breen are among the most recent powers to emerge on the galactic stage, and have used their relatively peripheral geopolitical standing to their advantage, bending events to their will from a safe distance and at a minimum investment of soldiers and treasure. Of special note are Breen weapons, which are extremely powerful and more than a match for any phaser or disruptor.</String>

The game is automaticly adding line breaks....where there are none. Thats the issue. I have come across it too.

I kinda solved this issue by "adding" line breaks. The window in the faction editor is (39) (41) 40 characters long so I added a line break to reflect this and it displays alot cleaner.

        <Label>FACTION_BORG_Dec</Label>
        <String>Borg 'civilization,' inasmuch one could
        call it that, consists of a collective
        of individual lifeforms called drones
        which receive direction from a
        centralized hivemind through a
        sophisticated subspace network that
        ensures each member is given constant
        supervision and guidance.
        The Collective exists for one purpose:
        to achieve perfection of understanding
        and the elimination of the need for
        biological matter through the mindless
        consumption of worlds and technology
        as well as the aggressive forced
        assimilation of other species. The
        mental energy of the group
        consciousness can help an injured or
        damaged drone heal or regenerate
        damaged body parts or technology.
        The collective consciousness not only
        gives them the ability to share the
        same "thoughts", but also to adapt
        with great speed to defensive tactics
        used against them. With no real
        'culture' to speak of, Borg tourism,
        trade and diplomatic contact is often
        non-existent.</String>
