Description:
If user put some ouput (like 'echo Hello!' or 'celebrat' for output every time when BASH is started) into ~/.bashrc file some non-interactive operations can be fail.

For ex., my .bashrc file:
---- cut here ----
alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

test -n "$DISPLAY" && export TERM=xterm-color

export PATH=$PATH:~/bin

export EDITOR=vim

# Output dates
echo
celebrat
echo
---- cut here ----

And if I try to copy file from another computer via 'scp' it fail: scp ask me for password but after Enter-press I see two new line on screen and info from celebrat. Solution for fixing this issue (from Debian Etch): add next lines:
---- cut here ----
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
---- cut here ----
at the begin of .bashrc so... For new users it line should be placed into skel data and /etc/skel/.bashrc should be fixed.

Additional info:
* package version(s): bash 3.2.033-2
* config and/or log files etc:


Steps to reproduce:
1. install bash and openssh
2. create new user (alex, for ex.) and set bash as user-shell
3. add 'echo Hi Alex' to end of ~/.bashrc
4. start openssh daemon (/etc/rc.d/sshd start)
5. log in to anther computer and try to copy some file via scp to user alex:
scp some_file.txt alex@test_host:
EXPECTED RESULT: file copied
ACTUAL RESULT: 'Hi Alex' text is shown on screen, file is not copied.
