I think the interaction between multiple selectors, especially when
some of them are negated, are much better explained in this version,
compared to the previous round in the README.

But I still think that the negation a feature that is unnecessary
and having it makes it harder to understand for users, especially
after reading this part:

The initial !3 means the same thing as "1-2,4-", and then 1-4 will
do what to that set?  The answer is "It is added"... wouldn't the
reader expect then that the result should be "1-", not "1-4"?  I
myself wondered what would happen to the fifth test from your
description.  Has the text told the reader that t9200 test has only
four tests?

The need to explain better with longer description will reduce the
likelyhood that the feature is understood and correctly used.  When
you can write "1-2,4-", why accept "1-4 !3" and force yourself to
explain to people why that is different from "!3 1-4"?
