I used to use the "open a rust-lang/rust issue" link a lot to be able to quickly copy pre-formatted example code, a playground link, and stdout, but that feature was removed due to it being used for spam (#671).

It would be nice to have a replacement feature where it would let me copy what used to go into the GitHub issue body. E.g., it would output this to a textbox that could be copied:

Code ([playground](...)):

```rust
...
```

Output:

```
...
```

This would actually be even more useful to me than the old "open a rust-lang/rust issue" link because I often want to use the output in Zulip messages or issue or PR comments.
