LLDB `v --ptr-depth 1` can't dereference pointer to a struct

[kerty0]

I tried this code:

struct S(i32);

fn main() {
    let s = &S(1);
    println!("Hello, world!");
}

When using LLDB with nightly Rust's pretty printers, I expect v --ptr-depth 1 to dereference the pointer to the struct and display its contents:

Process stopped
* thread #1, name = 'pp', stop reason = step over
    frame #0: 0x0000555555568bd0 pp`pp::main::hf3117127974a188e at main.rs:5:5
   2   	
   3   	fn main() {
   4   	   let s = &S(1);
-> 5   	   println!("Hello, world!");
   6   	}
(lldb) v --ptr-depth 1
(pp::S *) s = 0x0000555555559a84 {
  __0 = 1
}

Instead, it only prints the pointer address:

Process stopped
* thread #1, name = 'pp', stop reason = step over
    frame #0: 0x0000555555568bd0 pp`pp::main::hf3117127974a188e at main.rs:5:5
   2   	
   3   	fn main() {
   4   	   let s = &S(1);
-> 5   	   println!("Hello, world!");
   6   	}
(lldb) v --ptr-depth 1
(pp::S *) s = 0x0000555555559a84

This regressed in c39ebea

I'm not familiar with lldb, do you think just revert c39ebea would be enough to fix it and would be it reasonable, because from what I see author had a motivation to do this change and it was accepted? Also there is an interesting comment (#145218 (comment)) under this PR which shows few regression from this change and propose a better solution, but I'm not specialized in lldb to fully understand it
