You're right, Fredrik, but we (graciously as a group :) take also notice of
the other requirements that the OP has provided elsewhere and that are not
covered by the simple test that he specified.

The code above works for "aaaab" too, which the OP has already ruled out,
and it doesn't work for "aaa".
