Hm, this diverges from the behavior of (m)ksh and (soon) bash:

	% cat ./nofork_test; echo
	echo "$KSH_VERSION$BASH_VERSION$ZSH_PATCHLEVEL"
	foo=${ echo abc; }
	typeset -p foo

	% ksh ./nofork_test; echo
	Version AJM 93u+ 2012-08-01
	foo=abc

	% mksh ./nofork_test; echo
	@(#)MIRBSD KSH R59 2020/10/31
	typeset foo=abc

	% Reference/bash/bash ./nofork_test; echo
	5.3.0(2)-devel
	declare -- foo="abc"

	% zsh/zsh/Src/zsh ./nofork_test
	zsh-5.9-342-gdde1259
	typeset foo=$'abc\n'

If this is intentional, then it might be worth mentioning in the
FAQ, to warn users who are used to the other behavior.
