Bug#611487: xterm: immediately exits upon running: exec login USER

Package: xterm
Version: 261-1
Severity: normal

Hi,

First of all, please note that I currently have xterm Version: 235-2
installed.

With xterm Version: 261-1 installed, when I run this command,

$ exec login USER

the xterm immediately exits. This problem does not occur with prior
versions of xterm installed, eg, Version: 235-2.

Note that on my system, login is setuid root, thus enabling exec-ing
login from the base level shell, on e.g., tty1, pts/2, to work.

$ ls -l /bin/login
-rwsr-xr-x 1 root root 36896 Sep 25 18:05 /bin/login

Here is a typescript of the correct xterm behavior using Version: 235-2.
