The original code expects the Unicode stream from pipe doesn't
contains the Unicode BOM.
But that's not true.
Commit [9ed21946c7] changes
CreateFileInterfaceMem() to add the BOM for Unicode stream.
When parse pipe support was firstly added, a private implementation
ParseReturnStdInLine() was created to specially handle
the Unicode stream without BOM. Since now the Unicode steam contains
BOM, the private implementation can be removed and
ShellFileHandleReturnLine() can be used directly.
