Bash Version: 5.1
Patch Level: 16
Release Status: release

Description:
        Bash internal command cd doesn't ignore additional arguments
following dir as stated in its man page.
        This is not OS dependent, reproducible on Linux/FreeBSD since
version 4.4.

Repeat-By:
        $ cd /tmp /root
        -bash: cd: too many arguments

        While cd-ing to more dirs doesn't make sense this issue was
discovered by some bad regex in SAP profiles.
        bash before 4.4 was silently ignoring this.

        If this is expected behavior man page should be updated as those
arguments are not ignored any more.
