patch with a fix

When running
ssh -1 -tt user@host tty </dev/null

then ssh has to use SSHv1 and is forced to allocate a tty
even when stdin is not a terminal.

In this case, ssh correctly logs into the remote host,
allocates a tty and successfully runs the command.
But it displays error message:

tcgetattr: ......

Note that when SSHv2 is used, no error message is printed.
This is because the following two bugs were fixed previously:
https://bugzilla.mindrot.org/show_bug.cgi?id=1686
https://bugzilla.mindrot.org/show_bug.cgi?id=1199

This bug report is for SSHv1 only.
See the attached patch for a suggested fix.

We fixed this by deleting SSHv1 :)
