  | Maybe it should print "$HOME is not set" in that case?

Did you try it?

It is easy...

	(unset HOME; sh -c cd)

or use ksh (or some other shell) instead of sh to test it.

Note HOME  not $HOME  is not set, $HOME is, if
HOME is set, a pathname, or if HOME is not set, "",
neither of which makes any sense to describe as 'not set'.
