(That's what I meant -- the "-positions" name always confused me.)

OK, I fixed it.  A counter is only needed for the second use of
add-swindle-languages, which adds languages based on additional files
it might find in the collection.

When I did that I noticed that there is a bug in the easter egg code:
if you make a mistake, then afterwards the "mars" image is not
trigerred.  I fixed that.
