Todd Thomas b345aa9cbf Fix typo in hint for move_semantics1.rs.
When I compile the unedited example in the playground, I get the
error on line 10, not line 8. That's the case for stable, beta,
and nightly.

// So you've got the "cannot borrow immutable local variable `vec1` as mutable" error on line 10,
// right? The fix for this is going to be adding one keyword, and the addition is NOT on line 10
// where the error is.
