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.
