Description of problem:
When scp is invoked noninteractively (from cron, at, etc.) to copy between two
different machines, it prints an annoying and useless message:

Pseudo-terminal will not be allocated because stdin is not a terminal.

Options -qB that clearly indicate the intent of quiet batch processing do not help.


Version-Release number of selected component (if applicable):
openssh-clients-4.3p2-4


How reproducible:
Always


Steps to Reproduce:
1. touch test
2. scp -qB localhost:test localhost: </dev/null

  
Actual results:
Pseudo-terminal will not be allocated because stdin is not a terminal.
Permission denied (publickey,keyboard-interactive).


Expected results:
Permission denied (publickey,keyboard-interactive).


Additional info:
The purpose of </dev/null in the test case is to simulate non-tty stdin, as the
real-world noninteractive use cases would involve more complex setup.
