Code formatting: newlines before and after if statement block about dscresource.tests HOT 1 OPEN

I like to have air in the code so it easier for new contributors to read the code, it is easier for the eyes to see blocks, and those blociks are written the same throughout a repo. Most code is written with air, but there are no specific guideline around it (see https://github.com/PowerShell/DscResources/blob/master/StyleGuidelines.md#whitespace). But I love to see this as a guideline and a new custom rule (and more custom rules for the entire style guideline).

So this

$something = $true
if ($something)
{
}
if ()
{
}

I would rather see written as

$something = $true

if ($something)
{
}

if ()
{
}

With the exception of the previous line starts with an open brace. I like to see this as valid.

$something = $true

try
{
    if ($something)
    {
    }
}

from dscresource.tests.
