Strange indeed, assuming you tested on GNU/Linux or another POSIX
system, since IIUC on MS-Windows system-users returns only
user-real-login-name (at least it does here on Emacs 25.3 under Windows
8).  I also tested on another GNU/Linux system I have with Emacs 24.3
and see exactly the same behavior I described above.
