There was a problem hiding this comment.
OK, this was non-obvious, but it looks like there are no cases in which this would change observable behavior.
"No ;", "1 ;", "2 ;" and ">2 ;" should all be treated same due to contexts in which parse_full_stmt is used.

Do not consume semicolon twice while parsing local statement
The span for a `let` statement includes multiple semicolons. For example,
```rust
let x = 2;;;
// ^^^^^^^^^^^ The span for the above statement.
```
This PR fixes it.
