Dylan DPC 80045d65e1 Rollup merge of #96421 - nnethercote:less-NoDelim, r=petrochenkov ... Less `NoDelim` Currently there are several places where `NoDelim` (which really means "implicit delimiter" or "invisible delimiter") is used to mean "no delimiter". The name `NoDelim` is a bit misleading, and may be a cause. This PR changes these places, e.g. by changing a `DelimToken` to `Option<DelimToken>` and then using `None` to mean "no delimiter". As a result, the *only* place where `NoDelim` values are now produced is within: - `Delimiter::to_internal()`, when converting from `Delimiter::None`. - `FlattenNonterminals::process_token()`, when converting `TokenKind::Interpolated`. r? ````@petrochenkov````		2022-04-28 02:40:34 +02:00
