.ps1 shims don't work as expected with PowerShell 7 chain operators

[ocitrev]

With PowerShell 7 you can use chain operators. Without a proper value in $? it does not work as expected.

When I run this command line:

PS> should-fail || echo "Failed"

I get no output.
With current shims, PowerShell always see success (with automatic variable $?) when running .ps1 shims.

As a workaround, I can add .exe to the name of the command. This will bypass the .ps1 shim and work as expected.

PS> should-fail.exe || echo "Failed"
Failed

In case any one wants to try should-fail.exe, here is the source code.

int main() { return 1; }
