893ade3fac - fix PR1620, -DNO_HISTORY did not work.
- restore parsing state after parsing old style command substitution.
  The ';' in '`echo z;`' broke the following:
	for i in 1; do
		cat > /dev/tty << __EOF__
		`echo z;`
		__EOF__
	done

67893cfee5 IEEE 1003.2 (D11.2.2.3) requires that the system's true and false be accessed
