Description of problem:
When you-cron updates my machine with new selinux-policy, it sends some asterisks by email. Previous releases didn't do this.
Please, do not display asterisks when it's runnind from cron (in quiet mode
or if no tty, ...) or send them to output which is ignored by yum-cron
(I am not sure if this helps).

Version-Release number of selected component (if applicable):
policycoreutils-sandbox-2.1.11-18.fc17.x86_64
selinux-policy-targeted-3.10.0-132.fc17.noarch

policycoreutils-python-2.1.11-18.fc17.x86_64

How reproducible:

Steps to Reproduce:
