RHEL 7.3 error: SSH Cipher remediation broke after "Evaluate $sed_command" commit ad40f51

eval sed -i 's/^Ciphers./Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc/g' /etc/ssh/sshd_config
evaluates into (shown set +x output)
++ sed -i 's/^Ciphers./Ciphers' aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc/g /etc/ssh/sshd_config
which fails with a message:
sed: -e expression #1, char 20: unterminated `s' command

Without eval works fine.

I ran into this error running the latest scap_security_guide remediation with
centos-release-7-3.1611.el7.centos.x86_64
