Improve conflicting rlibs error again

Now you can do `rm <paste>` and 🐇💨

`--no-deps` filled in with a little more information. Explain that
`--fix` implies `--no-deps`.
Explain that `--no-deps` is used with `cargo clippy --`, including
one example.
Add missing whitespace after attribute in HTML template
Firefox (even though it worked) highlights it as red when you look at the source code because there is a missing whitespace.

Notify the Rust 2021 edition working group in zulip of edition bugs
Notifying the group of these issues will make it easier for us to track them.

Remove unnecessary `structhead` parameter from `render_union`
`structhead` is used for `render_struct` so that the logic for rendering
structs can be shared between struct variants and struct items. However,
`render_union` is not used anywhere except for rendering union items, so
its `structhead` parameter is unnecessary.
Fix help message for modification to &T created by &{t}

```rust
error[E0594]: cannot assign to `*x` which is behind a `&` reference

Prefer a code snipped over formatting the self type (`new_without_default`)
Fixes: rust-lang/rust-clippy#7220
changelog: [`new_without_default`]: The `Default` impl block type doesn't use the full type path qualification
Have a nice day to everyone reading this 🙃
Some `clippy::author` improvements
changelog: none
* Use `Debug` instead of re-implementing it for some things
* Fix block trailing expression handing
* Don't double print on stmt/expr with `#[clippy::author]` attribute
- Accessing fields of a union require unsafe block
- As part of 2229 we don't allow precision where we need an unsafe block
to capture.
Fixes: #87378
r? @nikomatsakis
In the event a pattern starts with a leading pipe
the pattern span will contain, and begin with, the pipe.
This updates the process to see if a match arm contains
a leading pipe by leveraging this recent(ish) change to
the patterns in the AST, and avoids an indexing bug that
occurs when a pattern starts with a non-ascii char in the
old implementation.
* Updating outdated links
Updating the links to the docs and source code for `ast.rs`. Seems like it was moved to a new crate at some point.
* Updating more outdated links
This time, the links to the `fmt-rfcs` repository, which is now owned by
`rust-dev-tools` (although GitHub was redirecting anyway).
* Update Contributing.md

On stable, running with `--help|-h` shows information about `file-lines`
which is a nightly-only option. This commit removes all mention of
`file-lines` from the help message on stable.
There is room for improvement here; perhaps a new struct called, e.g.,
`StableOptions` could be added to complement the existing
`GetOptsOptions` struct. `StableOptions` could have a field for each
field in `GetOptsOptions`, with each field's value being a `bool` that
specifies whether or not the option exists on stable. Or is this adding
too much complexity?
This was added to Configurations.md in #4618, but the option wasn't
actually made available. This should let people who are using Rust 2021
on nightly rustc run `cargo fmt` again.
rename const checking visitor module to check_consts::check
This avoids naming ambiguities with "const validation" which is in `interpret/validity.rs` and checks *values*.
