Further improvement of make_greater_string. Make sure that it considers all the possibilities that the old code did, instead of trying only one possibility per character position. To keep the runtime in bounds, instead tweak the character incrementers to not try every possible multibyte character code. Remove unnecessary logic to restore the old character value on failure. Additional comment and formatting cleanup.
