[Discuss] SCP from STDIN: "-t" option undocumented?

[John Abreau]

In my case, I had a passwordless ssh key, and a validate-rsync script
to use in the key's "command=" prefix in the authorized_keys file.
I wanted to allow the same key to accept scp as well as rsync.
I discovered the -t option when I had the validate-rsync script write
the $SSH_ORIGINAL_COMMAND to a logfile in order to determine
how scp works behind the scenes.
