This was from a while ago, it never got installed.  Re-diffed below
for the current cvs and with the wording tweaked a bit (for less
change actually):

       The variable `fill-nobreak-predicate' is a hook (an abnormal hook,
    *note Hooks::) specifying additional conditions where line-breaking is
    not allowed.  Each function is called with no arguments, with point at
    a place where Emacs is considering breaking the line.  If a function
    returns a non-`nil' value, then that's a bad place to break the line.
    Two standard functions you can use are `fill-single-word-nobreak-p'
    (don't break after the first word of a sentence or before the last) and
    `fill-french-nobreak-p' (don't break after `(' or before `)', `:' or
    `?').

        * text.texi (Fill Commands): fill-nobreak-predicate is now a hook.
