Read-Host returns 'Input request cancelled' when hitting Enter key without typing any input

[rohancragg]

The following snippet in a Powershell Notebook cell reports an error if hitting the [Enter] key when prompted and does not behave as it would in a Powershell terminal (i.e. to return the value 'DEFAULT' without reporting an error):

$value = 'DEFAULT'
$value = if ($_ = Read-Host -Prompt "Enter value, or [Enter] to use default value - '$value'") {$_} else {$value}
$value

The error is

Read-Host: Line | 2 | … = if ($_ = Read-Host -Prompt "Enter value, or [Enter] to use default … | ~~~~~~~~~~~~~ | Input request cancelled DEFAULT
