"one of the three entries below asserts that a mutation is NOT noticed" is a
count of the entries it sits above, and the preamble's last line - and the file's
own docstring - say no count is kept here, because a count of the entries is a
second copy of them. The previous wording said "three", which was also wrong: one
entry is GREEN. Corrected to "three" would have been an accurate second copy;
the sentence now states the shape and counts nothing.
