¿Hay uno? (Quiero esto porque quiero crear el formato de índice 7 n.\,1si hay más de una nota en la página y 7\,n.
PD. Dicho más claramente, según lo solicitado: ¿se podría definir una macro \fnnonthispageque devolviera el número de notas a pie de página en la página actual? No sé cómo decirlo más claramente.
PD II. Así es como se podría utilizar la macro. En la primera página hay dos notas, por lo que la entrada debe especificar el número; pero de p. 2, solo hay uno, por lo que no se debe especificar el número. Si una página contiene una nota a pie de página parcial, también debería contar como una.

Aquí hay una solución. Comprobamos si hay más de una nota al pie en cada página de salida, si no \mtfnexiste<pagenumber>hay una macro definida.
NotaEl comentario anterior de John Kormylo es importante, pero no me preocupé del punto aquí. Hágamelo saber.
