As someone who has written a book for one of those publishers you
mention above, this is totally not an issue at all.  Authors and
typesetters know how to properly wrap and handle stuff like this
automatically, it's what they do and has nothing to do with how kernel
header files are layed out.

But even then, if it was an issue, we don't write kernel code for "some
potential commercial entity that can't handle long lines", you know
better than this :)
