Some image viewers, which rely on gtk+ to show images, are unable to show portable anymaps. gtk+ seems to rely on freedesktop.org.xml for file type detection, which fails for some anymaps.
Removing the lines about # solves this, and here "man 5 ppm" does not say a comment is needed (although it can exist).
