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.

This example isn't reproducible now since `ctrlc` upgrades `winapi` to `0.3.x` in `3.1.1`. We should pin their versions to trigger lint correctly.

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
```

Closes #4399
changelog: dont fire `possible_missing_comma` if intendation is present

I suspect there is already a utils function for indentation (but searching indent didn't yield a function for that), and my solution is certainly not universal, but it's probably the best we can do.

changelog: add size threshold for the `vec_box` lint, currently 4096 bytes (one page) (subject to change). Closes #3547.

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 ?
