rustc considers the following valid and without a shebang:
```rust
// Hello
[allow(dead_code)]
fn main() {
println!("Hello, world!");
}
```
and
```rustc
[allow(dead_code)]
fn main() {
println!("Hello, world!");
}
```
In both cases, we consider it to have a shebang. This commit documents
that intention.
We could add our own heuristics
(e.g. `#!` with only whitespace is not a shebang)
but we should either be a subset or intentionally different than rustc
(e.g. require a non `[`-prefixes interpreter)
rather than do both.
This will be reflected in the tracking issue which will handle the final
decision for the team on this matter.
Fixes rust-lang#15170
