blance 0805011ac6 Show a preview of blocked/substituted downloads in Get-WinSCP.ps1
The 1MB size-check catches a bad download but gave no way to see why - on a
locked-down network something is very likely substituting a small HTML page
(proxy/AV block page) for the real zip. Print the first lines of whatever
was actually saved so the content is visible without another round trip.
