Extend no-multi-spaces with allow alignment option

Is it possible to have a rule to allow alignment of = (which introduces multi spaces) without having to turn off no-multi-spaces?

The following would be considered a warning:

var a   = 1;

var a    = 1;
var bar = 1;

The following would not:

var a   = 1;
var bar = 1;

Currently no-multi-space complains about what ESLint calls good coding conventions:

// Good
var count   = 10,
    name    = "Nicholas",
    found   = false,
    empty;

I agree that this is good, but turning off no-multi-spaces completely is a blunt instrument that would hide warnings you want.

What about for aligning literals in function calls?

foo('one',   'two',   'three')
foo('four',  'five',  'six')
foo('seven', 'eight', 'nine')

I think there has to be a smarter option than just ignoring a whole class of node for this type of alignment. Shouldn’t it be possible to compare the start prop of the AST?

Try astexplorer.net to inspect the syntax tree from a number of popular parsers. @alexilyaev in your case with babel-eslint, it looks like you want ClassProperty.
