[Bug 2019010] Re: environment variable SSH_ORIGINAL_COMMAND on server side set with wrong value

[Andrey]

Hello
I so that when it  using scp with -O option " Use the legacy SCP protocol ..." it is working.
The problem is that it is not always possible to force client to use additional switch.
it is many cases when  SSH_ORIGINAL_COMMAND is checked on server and additional decision is made on it . Is it possible to  set this variable on server side to "original" meaning  even when SFTP protocol is used for file transfer ? 
Thnaks.
