Rollup merge of #124389 - CensoredUsername:master, r=petrochenkov
Add a warning to proc_macro::Delimiter::None that rustc currently does not respect it.

It does not provide the behaviour it is indicated to provide when used in a proc_macro context.

This seems to be a bug, (https://github.com/rust-lang/rust/issues/67062), but it is a long standing one, and hard to discover.

This pull request adds a warning to inform users of this issue, with a link to the relevant issue, and a version number of the last known affected rustc version.
