Shift+Space not working in Powershell

It seems like you need to update the PowerShellGet and PSReadLine Module to make shift+space work again.

1. Open PowerShell as admin
2. Run install-module -name powershellget -force
3. Restart PowerShell (as admin)
4. Run install-module -name psreadline -allowprerelease -force
5. Restart PowerShell again

This should do it and it should work again.

This seems to be "broken" again in PowerShell 5.1.x. That is, Get-PSReadLineKeyHandler shows no mapping associated with Shift+Spacebar, and pressing shift+space has no effect whatsoever.

Explicitly enabling it with Set-PSReadLineKeyHandler -Chord Shift+Spacebar -Function SelfInsert fixes the issue (pressing shift+space inserts space character), but the mapping will not show in the Get-PSReadLineKeyHandler listing as is, but as plain Space mapping.
