Description
❯ rustfmt --version
rustfmt 1.8.0-stable (4d91de4e48 2025-02-17)
Consider the following file foo.rs:
fn f() {} // This has trailing whitespace
The trailing whitespace remains when calling rustfmt --edition 2024 foo.rs but rustfmt foo.rs removes it.

Research direction
Start by reproducing the difference with the shown foo.rs input, comparing rustfmt foo.rs with rustfmt --edition 2024 foo.rs. Trace how the edition option reaches formatting and verify that the trailing spaces are removed in both commands; done means the 2024 invocation matches the default behavior.
