README: sort en/disabling section, fix typos, add note

it took me a while to figure out why `cargo clippy -- -Aclippy::pedantic -Wclippy::items-after-statements` still showed me *all* the lints. At first I thought it was due to the missing spaces in the current example and I debugged that until I stumbled across an issue noting that you have to touch a random file or run `cargo clean` when you're running clippy repeatedly on an unchanged codebase. This PR is an attempt to save the next person some time and also structure the "Allowing/denying lints" section a bit more while we're at it.

@ -169,12 +169,33 @@ You can add options to your code to `allow`/`warn`/`deny` Clippy lints:
Note: `deny` produces errors instead of warnings.
If you do not want to include your lint levels in your code, you can globally enable/disable lints by passing extra
flags to Clippy during the run: `cargo clippy -- -A clippy::lint_name` will run Clippy with `lint_name` disabled and
`cargo clippy -- -W clippy::lint_name` will run it with that enabled. This also works with lint groups. For example you
can run Clippy with warnings for all lints enabled: `cargo clippy -- -W clippy::pedantic`
If you do not want to include your lint levels in your code, you can globally enable/disable lints
by passing extra flags to Clippy during the run:
To disable `lint_name`, run
```terminal
cargo clippy -- -A clippy::lint_name
```
And to enable `lint_name`, run
```terminal
cargo clippy -- -W clippy::lint_name
```
This also works with lint groups. For example you
can run Clippy with warnings for all lints enabled:
```terminal
cargo clippy -- -W clippy::pedantic
```
If you care only about a single lint, you can allow all others and then explicitly reenable
the lint(s) you are interested in: `cargo clippy -- -Aclippy::all -Wclippy::useless_format -Wclippy::...`
the lint(s) you are interested in:
```terminal
cargo clippy -- -A clippy::all -W clippy::useless_format -W clippy::...
```
Note that if you've run clippy before, this may only take effect after you've modified a file or ran `cargo clean`.
