I'll need to see if I can come up with a minimal example, because I cannot
show the actual code, unfortunately. However, the buffer contains a series
of images, one per line, with newlines in between. The images are higher
than the frame's character height, though I don't know if that's relevant.
They also all have `:ascent` set to 100, so they sit on the base line.

The last line of the buffer has a single newline without additional text.
Placing point at `(1- (point-max))` puts it right after the last image, so
`(recenter -1)` should, IIUC, place the image right above the window
bottom, with the final empty line invisible (or at least partially
invisible). But in actual fact that line is still completely visible. I can
move the cursor to it without causing any scrolling.
