padded blocks should allow single lines.

[allanchau]

I've been following #7145 and other similar issues and thought the option allowSingleLineBlocks would fix this. I am actually looking for a rule which:

• Disallows padding (new lines) if the code within the block is only a single line.
• Force padding if the code within the block spans multiple lines.

What rule do you want to change?

padded-blocks

Does this change cause the rule to produce more or fewer warnings?

Fewer.

How will the change be implemented? (New option, new default behavior, etc.)?

New option.

Please provide some example code that this change will affect:

// correct
if (cond) {
    doSomething();
}

if (cond) {

    doSomething()
        .then(...)
        .catch(...);

}

// incorrect
if (cond) {

    doSomething();

}

if (cond) {
    doSomething()
        .then(...)
        .catch(...);
}

What does the rule currently do for this code?

Warn or nothing depending on the settings.

What will the rule do after it's changed?

Produce less warnings.

Are you willing to submit a pull request to implement this change?

Sure, but I wouldn't know where to get started 😄 .

[eslint-deprecated]

Unfortunately, it looks like there wasn't enough interest from the team
or community to implement this change. While we wish we'd be able to
accommodate everyone's requests, we do need to prioritize. We've found
that issues failing to reach accepted status after 21 days tend to
never be accepted, and as such, we close those issues.
This doesn't mean the idea isn't interesting or useful, just that it's
not something the team can commit to.

Thanks for contributing to ESLint and we appreciate your understanding.
