nit: Should this be "turned off" rather than "turned of" (and
"individual tests" rather than "individual test").
It _may_ be worth re-wording it to explain the "if !KUNIT_RUN_ALL"
change in more detail: that it's explicitly hiding the prompt if
KUNIT_RUN_ALL is enabled.
It's probably not worth redoing the patch just for this, but if you've
got to re-do all these to change KUNIT_RUN_ALL to KUNIT_ALL_TESTS or
similar, maybe.
