… then, the C version of the algorithm is in this file:

https://foundry.supelec.fr/scm/viewvc.php/trunk/source/texk/web2c/luatexdir/lang/texlang.w?root=luatex&view=markup

find_next_wordstart() and valid_wordend() are the most important tests, but there
are a few extra inline tests done in hnj_hyphenation().
