OK, seems I've been fooled:
[helmut@BSDHelmut ~]$ which cd
/usr/bin/cd
[helmut@BSDHelmut ~]$
I too late looked at /usr/bin/cd a bit closer:
[helmut@BSDHelmut ~]$ file /usr/bin/cd
/usr/bin/cd: POSIX shell script text executable
[helmut@BSDHelmut ~]$ cat /usr/bin/cd
#!/bin/sh
# $FreeBSD: src/usr.bin/alias/generic.sh,v 1.2.10.1.6.1 2010/12/21
