identify with multiple images

This follows a thread in Users: viewtopic.php?f=1&t=26809
The behaviour for "identify" changed between 6.8.0-0 and 6.8.9-0. The effect of the change is such that if the format string contains %n (the number of images), the rest of the format string is no longer repeated, once per image. I think this new behaviour is a bug.
This new behaviour applies to "identify" but not "convert -ping" (in 6.8.9-0 and 6.9.0-0). This still gives the old behaviour, issuing a format for each image, even when the format string contains "%n".
Bad behaviour of current "identify":
Good behaviour of current "convert -ping":
