Well, to be specific, I am re-encoding interlaced 720x480 material.
Unfortunately, it needs to be playable by programs and hardware that
don't understand aspect, so I have to scale it.
If I do scale=-1:-2, it will scale up the height to 540, which will
competely ruin the interlacing. So, I wanted to use scale=-2:-1 to
keep the height the same, and scale only the width.
Since that does't work, I've been using scale=-2:480, which works, but
different material has different heights, so I have to manually change
the 480 to match each individual video. If scale=-2:-1 worked, it would
help a lot.

Well, I expected this was an actual bug, because scale=-1:-2 will work
fine, but scale=-2:-1 does not...
