Possible formatting issue related to unary operators

[AWahlqvist]

Issue Description

So I opened this bug at the VSCode repo:
PowerShell/vscode-powershell#1237

It's about unary operators that (from what I can tell), aren't handled correctly when formatting the code.

This:

$numberOfDaysToSubtract = 10
(Get-Date).AddDays(-$numberOfDaysToSubtract)

Becomes this:

$numberOfDaysToSubtract = 10
(Get-Date).AddDays( - $numberOfDaysToSubtract)

When formatting the code in VSCode with powershell.codeFormatting.whitespaceAroundOperator set to true.

I got a response from @tylerl0706 who clarified that this formatting actually comes from PSSA, which is why I created a bug here instead.

What do you think?

Thanks!

Thanks for taking the time to report this issue. This is a duplicate of #847 and I believe it is by design because the setting whitespaceAroundOperator does exactly what it is supposed to do.
I can understand however that the resulting formatting is not desired in this case,
PSSA has 3 built in rule sets (Allman, etc.) that VSCode uses as well and I think the best solution would be to tweak them and to come up with a more refined ruleset that allows certain exceptions like this case.

Yes, it does seem to be a duplicate, sorry, missed the other one. Will focus any discussions to that bug instead.

Thanks!
