Incorrect unresolved module error/actions for submodules under raw identifiers

[delan]

rust-analyzer version: 0.3.1186-standalone (e8e598f 2022-08-28)

rustc version: 1.65.0-nightly (ce36e8825 2022-08-28)

Create a project with cargo new --bin foo.

Given the following src/main.rs, the rust-analyzer(unresolved-module) and code actions correctly suggest creating “const.rs” or “const/mod.rs”.

mod r#const;
fn main() {}

But given the following src/const.rs, they suggest creating “r#const/foo.rs” or “r#const/foo/mod.rs”, even when src/const/foo.rs or src/const/foo/mod.rs exists.

mod foo;

If we rename src/const/foo.rs to src/r#const/foo.rs as suggested, the rust-analyzer(unresolved-module) goes away, but we now have a rustc(E0583) essentially telling us to rename it back, so it looks like including “r#” in module filenames is incorrect.
