CL 65851 (bytes) and CL 65910 (strings) “improve[d] readability”
by removing the special case that bypassed the whole function body
when chars == "". In doing so, yes, the function was unindented a
level, which is nice, but the runtime of that case went from O(1) to O(n)
where n = len(s).
I don't know if anyone's code depends on the O(1) behavior in this case,
but quite possibly someone's does.
This CL adds the special case back, with a comment to prevent future
deletions, and without reindenting each function body in full.

This should help make clear that Len is not counting runes.
Also delete empty string, which doesn't add much.

`bytes` and `strings` are pretty similar to each other, this commit
brings `strings` examples to its counter-part.
Partially addresses #16360
