I would have thought something like this would work:
(defun nobreak-p ()
(interactive)
(let ((result (if (and (looking-at " ")
(save-excursion
(re-search-forward "[^{]*}" (line-end-position)
'end))
(save-excursion
(re-search-backward "[^}]*\\\\index{"
(line-beginning-position) 'end)))
t
nil)))
(message "%s" result)
result))
(add-hook 'fill-nobreak-predicate #'nobreak-p)
at least, from what I can see it returns true everywhere it should not
break, but I still get breaks where I do not want them. maybe it could
give you an idea though.
