The two rules within it can and should be done without the separate
media query:
* There ain't no rule saying a viewport can't be `700.5px` wide, since
hardware pixels can be finer than CSS pixels.
* The rule for the first example-wrap child should probably apply
on mobile.
* The rule for the source sidebar is overriden by the mobile rule
setting `max-width: 100vw`, so it can be merged with the rest
of the styles.
Do not register placeholder `RegionOutlives` obligations when `considering_regions` is false
**NOTE:** I'm kinda just putting this up for discussion. I'm not certain this is correct...?
This was introduced in [`608625d`](608625dae9 (diff-6e54b18681342ec725d75591dbf384ad08cd73df29db00485fe51b4e90f76ff7R361)).
Interestingly, we only check `data.has_placeholders()` for `RegionOutlives`, and not for `TypeOutlives`... why? For the record, that different treatment between `RegionOutlives` and `TypeOutlives` is why the fix "The compiling succeeds when all `'a : 'b` are replaced with `&'a () : 'b`" in #100689 _"works"_, but it seems like an implementation detail considering this.
Also, why do we care about placeholder regions being registered if `considering_regions` is false? It doesn't seem to affect any UI tests, for example.

Add `unused_format_specs` lint
Currently catches two cases:
An empty precision specifier:
```rust
// the same as {}
println!("{:.}", x);
```
And using formatting specs on `format_args!()`:
```rust
// prints `x.`, not `x .`
println("{:5}.", format_args!("x"));
```

remote-test-server: Show command line arguments
The user of remote-test-server should get at least some minimal command line help as this is often started manually.

Sometimes it is convenient to return a subdiagnostic enum where one or
more of the variants don't add anything to the diagnostic.

Documentation comments shouldn't affect the diagnostic derive in any
way, but explicit support has to be added for ignoring the `doc`
attribute.

* Since it's used exclusively on source pages, no need to explicitly
select.
* No need to hide it when the sidebar is open, since it fills the whole
page.
