Comma in indexing expression produces incorrect error location and suggestion to add a semicolon

Code

fn example() {
    (foo[
        bar
        .baz(),
    ])
}

Current output

error: expected `;`, found `[`
 --> src/lib.rs:2:9
  |
2 |     (foo[
  |         ^
  |
help: consider adding `;` here
  |
2 |     (foo;[
  |         +

Desired output

error: expected `]`, found `,`
  |
4 |         .baz(),
  |               ^

Rationale and extra context

The existing error message points to the wrong line, and suggests that a semicolon could help, when in fact it would make things worse.

Other cases

This problem is sensitive to line breaks — it does not happen if the extra comma is on the same line as foo.
