You can use Path.PathSeparator.

I thought that the PWD got appended to the end of PATH so I didn't want it on both ends, looks like that isn't the case. I'll remove.

We should check if the first path in $env:PATH is pshome, and only insert if it's not. Otherwise, the nested powershell instance will have 2 pshome paths in $env:PATH
