`cargo clippy --fix` fails to fix unneeded return

[Seeker14491]

Running cargo clippy --fix fails to fix the following code:

fn f() -> i32 {
    {
        return 0;
    };
}

It tries to convert the return 0; into an implicit return, but it fails to remove the semicolon on the following line, which causes the error.

Full Output

$ cargo clippy --fix
    Checking rustfmt-debug v0.1.0 (/home/seekr/Desktop/rustfmt-debug)
warning: failed to automatically apply fixes suggested by rustc to crate `rustfmt_debug`

after fixes were automatically applied the compiler reported errors within these files:

  * src/lib.rs

This likely indicates a bug in either rustc or cargo itself,
and we would appreciate a bug report! You're likely to see 
a number of compiler warnings after this message which cargo
attempted to fix but failed. If you could open an issue at
https://github.com/rust-lang/rust/issues
quoting the full output of this command we'd be very appreciative!
Note that you may be able to make some more progress in the near-term
fixing code with the `--broken-code` flag
