One example to describe how `*` works actually prints a warning: ``` $ ruby -we "sprintf('%d', 20, 14)" => -e:1: warning: too many arguments for format string ``` I think it's better to not use examples that print warnings, so I propose to merge `*` docs with "width" specifier docs, and only include the "correct" example. After I believe `*` is not an actual flag, but a special value that the width specifier can take. Mention `*` special value in initial summary as well.
