I like the present (older) output because it's absolutely unambiguous. If I have to read a textual description to understand whether it's a default argument, whether it takes an optional parameter, or how precisely it is used, it's less clear especially when the text is badly written. The current output is probably also perfectly suitable for parsing (by a program).
