FWIW the current behavior -- while undocumented -- is aligned with
that of ksh, and this change would break that alignment and become
one more thing for ksh emulation to handle.

	% cd /bin
	% ksh -c 'print "$KSH_VERSION"; cd "" /usr'
	Version AJM 93u+ 2012-08-01
	/usr/bin
	% mksh -c 'print "$KSH_VERSION"; cd "" /usr'
	@(#)MIRBSD KSH R59 2020/10/31
	/usr/bin

The old behavior is not a bug, and the new behavior doesn't strike
me as particularly useful, so it's not clear to me that this would
be worth it (either as a breaking change or one hidden behind yet
another option).
