su: FEATURE_SU_BLANK_PW_NEEDS_SECURE_TTY
When this feature is enabled, blank passwords are not accepted by su unless the user is on a secure TTY defined in /etc/securetty. This resembles the default PAM configuration of some Linux distros which specify the nullok_secure option for pam_unix.so. Based on patch by Kaarle Ritvanen <kaarle.ritvanen@datakunkku.fi> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
