Auto merge of rust-lang#29441 - Ryman:match_refactor_msg, r=alexcrichton
This helps for the case where a match, such as below: ```rust let foo = match foo { Some(x) => x, None => 0 }; ``` gets refactored to no longer need the match, but the match keyword has been left accidentally: ```rust let foo = match foo.unwrap_or(0); ``` This can be hard to spot as the expression grows more complex. r? @alexcrichton
