Well, actually Emacsen are *text* editors, not word processors.  Long
lines are in fact a pain in the ass for almost everything I do, except
word processing (and even a lot of word processing -- ie, in multi-
backend structured text modes).  How does your "few lines in C" handle
reStructuredText, for example?  (It's those applications that make
long-lines modes so complex, you know.)  N.B. Emacs just got a real
long-lines mode with version 23, and they're still arguing about the
right defaults for it.

Please consider factoring the code so that it's easy to use the
Unicode UAX#14 line breaking algorithms in the future!
