Here Remove-Item is workaround for a bug. Is the bug already fixed?

Ah. I didn't know what "broken symlink issue" the author was referring to, so I didn't remove another dev's code. I am working on a Remove-Item issue, but I want to get this in so I can write tests using New-Item rather than shelling out a mklink command.

I guess it's about problem with recursion when there are symlink. It is seems already fixed. It is not related with your PR.
