use that without copying. This is helpful for expanding strings like
$message_headers which can get very long.
+There's a problem if a ${dlfunc item has side-effects that cause allocation,
+since resetting the store at the end of the expansion will free store that was
+allocated by the plugin code as well as the slop after the expanded string. So
+we skip any resets if ${dlfunc has been used. This is an unfortunate
+consequence of string expansion becoming too powerful.
