Johannes Altmanninger 30f821c8f4 Fix example in string length docs ...

Technically the equivalence would be something like

	string length -q $str
	test -n (string join \n -- $str | string collect)

To handle when str has multiple empty strings;
but quoting is easier to remember and enough for most practical purposes.
