fix typos
"the empty String" is an example of a value without identity
restore an "is *true*" mistakenly dropped by https://github.com/tc39/ecma262/wiki/Editorial-Conventions/_compare/186d189932260e1cf354ab574b7adc87fa1df0ac...b1a0bc5533d10bba0cd1ddfb70a6f9a5c7f6b67e
comparison against 3+ individual values still uses "one of" rather than "either"
Type comparison takes precedence over equality per https://github.com/tc39/ecma262/issues/3937
Fix typo
Reword Comparisons per https://github.com/tc39/ecma262/issues/3844
