Running the following from cmd.exe appears to do nothing. No output. No error   
   message.   
      
   C:>powershell -NoProfile -Command "& { Get-ChildItem -Path 'C:/src/t/' ^|   
   Remove-Item -Recurse -WhatIf }"   
      
   Removing the invocation operator appears to simply make the command be printed.   
      
   C:>powershell -NoProfile -Command "{ Get-ChildItem -Path 'C:/src/t/' ^|   
   Remove-Item -Recurse -WhatIf }"   
    Get-ChildItem -Path 'C:/src/t/' ^| Remove-Item -Recurse -WhatIf   
      
   The pipe (VERTICAL BAR) character is escaped. What's going on here?
