Research direction

No files or tests are named; start by locating the formatter's handling of CommandExpressionAst and compare it with the multiline examples in this issue. Done means multiline right-hand-side list or expression assignments receive the requested increased indentation without changing AST constructs that already manage their own indentation.

Written by the indexing model from the issue text.

Description

Indent (a multiline) righthand side (list) expression assignment.
Meaning, for a (multiline) Statements.Right CommandExpressionAst (as apposed to Ast's that have already their own embedded indention, as e.g. a PipelineAst), I would like the righthand side to (optionally?) increase the indent:

Wrong way (?)
$List =
'One',
'Two',
'Three'
Correct way
$List =
    'One',
    'Two',
    'Three'
Wrong way (?)
$4 = # or any lengthy variable name aka dot notation
2 + 2
Correct way
$4 = # or any lengthy variable name aka dot notation
    2 + 2
