If there were brackets in a string argument of a script it was always
interpreted as interpolation before the change. That lead to unexpected
outputs of such scripts. After this change arguments which are not
intended as interpolation (not starting with $) and containing brackets
will have implicitly added backticks for correct interpretation in the
scripts. This fixes #10908.

To fix other issues mentioned in #11035 I changed the deparsing logic.
Initially we added backticks for multi word variables and double quote
if there was \ or " in the string. My change would add double quotes any
time string starts with $ or contains any of character that might break
parsing. The characters I identified are white space, (, ', `, ",and \.
It's possible other characters should be added to this list.

I tested this solution with few simple scripts using both stand alone
arguments and flags and it seems to work but I would appreciate if
someone with more experience checked it with some more unusual cases I
missed.

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

allow empty string arguments (#9420)
# Description

I'm not sure if this is a good idea or now but I did it to fix #9418. It
allows you to pass empty string arguments like this.

file named foo.nu
```
def main [--arg: string = dog] {
  if ($arg | is-empty) {
    echo "empty string"
  } else {
   echo $arg
  }
}
```
`> nu foo.nu --arg ""`
or
`> nu foo.nu --arg=""`
this gives an error
`> nu foo.nu --arg`
this returns the default argument
`> nu foo.nu`

closes #9418

Use variable names directly in the format strings (#7906)
# Description

Lint: `clippy::uninlined_format_args`

More readable in most situations.
(May be slightly confusing for modifier format strings
https://doc.rust-lang.org/std/fmt/index.html#formatting-parameters)

Alternative to #7865

# User-Facing Changes

None intended

# Tests + Formatting

(Ran `cargo +stable clippy --fix --workspace -- -A clippy::all -D
clippy::uninlined_format_args` to achieve this. Depends on Rust `1.67`)
