[ESS] how to make close-parens indent identically to close-brace?

[Murat Tasan]

Ah, yeah, I hadn't thought of auto-insertion of closing braces (as I
always keep such auto-insertions off).

The common style (closing all parens at end of expression) works fine
until one finds themselves n functions deep in nesting (where n is,
say, > 3).
Adding optional arguments during development then becomes a serious chore.

This is particularly noticeable when using some R paradigms/frameworks
like Shiny, where nearly all presentation-control functions take
nothing but ... arguments, and where each argument itself is usually a
function that takes more ... arguments.

Is the code behind ess-dont-vertically-align-closing-paren on a
development branch of ESS?
I'd love to give it a try :-)

Cheers,
