Title sez it all: Can I detect, hopefully by inspecting
\box\footins, whether a footnote has been split at page-breaking?
I found the package fnbreak but it uses labels, which is much too delayed for my purpose.
I thought about a mark, but where would I put
Of course I could put a special penalty after every footnote and try to detect that with
\lastpenalty, but it seems like a cheap trick and furthermore, maybe it would be discarded?
What would you do?
