Option to tolerate single lines with padded blocks

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. Could be similar to { "allExcept": ["singleLine"] } in JSCS (http://jscs.info/rule/requirePaddingNewLinesAfterBlocks)

Please provide some example code that this change will affect:

if (cond) { doSomething(); }

What does the rule currently do for this code?

Warning / Error: “Block must be padded by blank lines.”

What will the rule do after it’s changed?

Emits no warning if using { "allExcept": ["singleLine"] } option

This seems like a good idea, but I don’t think allExcept: ["singleLine"] is a good API for it. An array containing a single string seems like an inelegant API to me; I think it would be better to have explicit object options instead.

How about something like this?

rules:
  padded-blocks: [error, always, {allowSingleLineBlocks: true}]

I know this has been accepted a while back, but I have a new proposal for this. How about deprecating existing blocks, classes and switches options, and adding exceptions option of type Array, that accepts ASTNode|"single"|"block"? That should cover all JSCS cases, and bring this rule inline with other rules we have.
