And an additional CSS adjustment to support dark mode for every inline code. It currently only works in paragraphs, which was an oversight on my part 😅. [Current Example](https://rust-lang.github.io/rust-clippy/master/index.html#blacklisted_name)

This also includes ~50 lines of doc comments and is therefor not as big as the changes would indicate. 🐧

changelog: none

All of these bugs were introduced in this dev version and are therefor not worth a change log entry.

7f2068cc2b Auto merge of #6568 - Jarcho:redundant_pattern_matching, r=flip1995
Fix: redundant_pattern_matching drop order

Fixes #5746

A note about the change in drop order is added when the scrutinee (or any temporary in the expression) isn't known to be safe to drop in any order (i.e. doesn't implement the `Drop` trait, or contain such a type). There is a whitelist for some `std` types, but it's incomplete. Currently just `Vec<_>`, `Box<_>`, `Rc<_>` and `Arc<_>`, but only if the contained type is also safe to drop in any order.

Another lint for when the drop order changes could be added as allowed by default, but the drop order requirement is pretty subtle in this case. I think the note added to the lint should be enough to make someone think before applying the change.

changelog: Added a note to `redundant_pattern_matching` when the change in drop order might matter

The other option here would be to add the return type to the closure. It would be fine for simple types, but longer types can be rather unwieldy. Could also implement the adjustment manually.

tabs_in_doc_comments: Fix ICE due to char indexing

This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.

More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.

This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output. But I don't think we handle those cases
anywhere in Clippy currently?

Fixes #5835
