Session code generator for PowerShell outputs un-escaped dollar signs in double quoted literals

The Powershell code generator encapsulates string literals in double quotes. If any of the values contain a dollar sign, Powershell will interpret this as a variable reference.

For example:

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "ftp.example.com"
    UserName = "myuser"
    Password = "pa$sword" # Accidental reference to '$sword' variable
    SshHostKeyFingerprint = "ssh-rsa 2048 0b:1e:4b:29:43:7e:a3:aa:f4:6b:fe:50:cb:32:f8:35"
}

An easy solution would be to use single quotes instead.

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = 'ftp.example.com'
    UserName = 'myuser'
    Password = 'pa$sword'
    SshHostKeyFingerprint = 'ssh-rsa 2048 0b:1e:4b:29:43:7e:a3:aa:f4:6b:fe:50:cb:32:f8:35'
}
