Panic when typing the names on a tuple: index out of bounds: the len is 0 but the index is 0 #16746
Description
When deleting characters from the name of one element in a tuple, if you delete the last one a panic will occur.
To reproduce, create a new empty project and add this to your main.rs:
fn main() {
let (a, b) = (0, 0);
}Then place your cursor right after the 'b' character and press backspace, making your code look like this:
fn main() {
let (a, ) = (0, 0);
}This panic message is printed to stderr.

(sidenote: I know this is the third issue about panics from me in the past 5 days, I apologize if I'm getting annoying)
