de-indent for Newline immediately following "("

[cgay]

What we have now:

let foo = really-long-function-name(
                                    long-argument-1(),
                                    long-argument-2())

What I want:

let foo = really-long-function-name(
             long-argument-1(),
             long-argument-2())

Note, never this:

let foo = really-long-function-name(argument-0-on-same-line(),
             long-argument-1(),
             long-argument-2())

If there's an argument immediately following the open paren then subsequent args should line up under the first (as they do currently):

let foo = really-long-function-name(long-argument-1(),
                                    long-argument-2())

Another language has gone for not doing things that line up like your last example ... that way, people can use non-monospace fonts if they like!

Do not want.

There's also a fair amount of this style, and Peter Housel prefers it over my first choice above:

let foo = really-long-function-name
              (long-argument-1(),
               long-argument-2())

and I think it should be possible to support both styles depending on whether the open paren is (a) preceded by all whitespace or (b) followed by only whitespace and comments.

I recently learned the term for what I want, and it is https://github.com/google/google-java-format/wiki/The-Rectangle-Rule
