Breaking lines on the right border

Inspired by the (bad line breaking) example above, Taco wrote the following macro, which breaks a line as soon as it doesn't fit to the box any more.

The second box may serve as an example of what to do when you become desperate about your German grammar and hyphenation rules.

% BREAK is a special pretty handler that auto-wraps lines
% to fit the current hsize.
