Which might explain why this silly mistake went unnoticed. (And, as I
think you implied, it doesn't help that the empty rule we're hitting
here is not commented.)

So the naive solution seems to be to also add the warning to COMMAND's
rule for '.'. A quick test suggest that would work. Am I missing some
obvious downside with that solution?
