Marking this as draft: it might be better to combine the section with the other displays. |

Split up and reword the sections for
group(except yield) andtuplerules inpython.gram.As is tradition in these PRs, simple/usual syntax comes first, followed by more complex and obscure cases, finishing up with the formal grammar.
For tuple displays, this meant putting tuples with 2+ elements first, followed by one-element and empty ones. I think the rules are much easier to follow this way.
This also fixes the formal grammar, which previously didn't allow commas in the parentheses.
