b5e6d6db41 Auto merge of #5134 - flip1995:snippet_block, r=phansch
Make it possible to correctly indent snippet_block snippets

This adds a `indent_relative_to` arg to the `{snippet,expr}_block` functions. This makes it possible to keep the correct indentation of block like suggestions.

In addition, this makes the `trim_multiline` function private and adds a `indent_of` function, to get the indentation of the first line of a span.

The suggestion of `needless_continue` cannot be made auto applicable, since it would be also necessary to remove code following the linted expression. (Well, maybe it is possible, but I don't know how to do it. Expanding the suggestion span to the last expression, that should be removed didn't work)

a39589480b Auto merge of #5129 - JohnTitor:use-checked-sub, r=flip1995
Use `checked_sub` to avoid index out of bounds

(Fixes) #4681 (possibly)

The issue likely occurs due to `lit_snip.len() < suffix.len() + 1`. You can see similar backtrace to change it to `lit_snip.len() - suffix.len() - 1000` or something then run `cargo test --release`.
But I couldn't come up with the test so I'd leave the issue open if we want.

8e9089e454 Auto merge of #5110 - Aloso:patch-1, r=flip1995
Fix syntax highlighting of code fences

The documentation for RESULT_EXPECT_USED includes this code:

    let res: Result<usize, ()> = Ok(1);
    res?;
    # Ok::<(), ()>(())

Because the code fence didn't start with `rust`, the code wasn't highlighted and the line starting with `#` was displayed on the website. This is now fixed.

EDIT: I noticed that highlighting for some other lints is broken as well. It only works if the code fence looks like this:

````markdown
```rust
// ..
```
````

However, many code blocks were ignored. I un-ignored most code blocks and made them compile by adding hidden code with `#`. While doing so, I found two mistakes:

```rust
opt.map_or(None, |a| a + 1)
// instead of
opt.map_or(None, |a| Some(a + 1))
```
and

```rust
fn as_str(self) -> &str
// instead of
fn as_str(self) -> &'static str
```

diff is a little bit confusing due to some refactoring (moving free functions to lint struct functions), relevant portion is [this](https://github.com/rust-lang/rust-clippy/compare/master...Areredify:vec_box_threshold?expand=1#diff-1096120ca9143af89dcc9175ea92b54aR294-R298).

Match wild err arm improvements

This lint should trigger on other identifiers which have `_` prefix (such as `_e`) and only if they are unused in the panic block.

_Note_: the `is_unused` function is greatly inspired from `pat_is_wild` function in [loops lints](43ac9416d9/clippy_lints/src/loops.rs (L1689)).
I've been considering doing some refactoring, maybe in utils. Maybe this PR or a new one. What do you think ?

Check if `Ty`s are normalizable. It might show hidden false negative, I'm not sure.
Also, the regression tests are placed on two dirs, so move them to `/crashes`. I think it will be easier to find the right place.
