Well, they can patent a product which inserts soft hyphens afterwards,
but I don't think they can prohibit to make groff directly embedding
soft hyphens in the document from the very beginning.  I can do that
right now using groff's macro capabilities -- Thomas Baruchel has
shown us how to do that kind of tricks: Set the line length to almost
zero, put the output into a diversion, handle it line by line (each
line now contains a word or a hyphenated part of a word), replace a
final hyphen with a soft hyphen (using .unformat and .substring),
etc., etc.
