Overview:
SSH modifies line endings when using command in authorized_keys.
I'm using keys to ensure that an unattended copy occurs while using the command="aScript.php" that outputs an uncompressed tarball. Because of the line endings changing, my tarball becomes invalid.

What happens:
When using public/private keys to force a particular command to run, under tested circumstances, LF is converted to CRLF.
Running the same command without using a forced command returns the correct text.

Steps to reproduce:

cd ~
echo this is a test > bugcheck.txt
echo It needs to have multiple lines >> bugcheck.txt
echo so that I can check if there is a bug >> bugcheck.txt
echo in OpenSSH >> bugcheck.txt
ssh-keygen -t rsa -f bugcheck -N ""
echo -n "no-port-forwarding,no-X11-forwarding,no-agent-forwarding,command=\"cat bugcheck.txt\" " >> ~/.ssh/authorized_keys
cat bugcheck.pub >> ~/.ssh/authorized_keys
ssh localhost 'cat bugcheck.txt' > bugcheck-response-1.txt
ssh -i bugcheck localhost > bugcheck-response-2.txt
ls -l bugcheck-response-*.txt

Actual Results:
-rw-r--r-- 1 codewarrior codewarrior  96 Nov 10 11:12 bugcheck-response-1.txt
-rw-r--r-- 1 codewarrior codewarrior 100 Nov 10 11:12 bugcheck-response-2.txt
(bugcheck-response-2.txt contains CRLF line endings)

Expected Results:
-rw-r--r-- 1 codewarrior codewarrior  96 Nov 10 11:12 bugcheck-response-1.txt
-rw-r--r-- 1 codewarrior codewarrior  96 Nov 10 11:12 bugcheck-response-2.txt
(bugcheck-response-2.txt should have original LF line endings)
