Allow linebreaks before closing parentheses?

[lucaswerkmeister]

I wrote the following code a while back:

variable Integer offset = options.indentMode.indent(
    tokenStack.fold(0, (Integer partial, FormattingContext elem) => partial + elem.postIndent)
).size;

(source, linked to the commit that introduced the code). The formatter turns this into:

variable Integer offset = options.indentMode.indent(
    tokenStack.fold(0, (Integer partial, FormattingContext elem) => partial + elem.postIndent)).size;

because a PositionalArgumentList doesn’t allow linebreaks before the closing parenthesis.

I’m not sure if that’s right.

After a bit more considering, I think that linebreaks should be allowed before a ).
