I think this "string to enum" parser can become a separate helper
function in this patch, so that later patch can use it to parse the
"--update" option in the update_clone() function.

That would solve the slight inconsistency we have seen

+		if ((pp->update && !strcmp(pp->update, "none")) ||
+		    (!pp->update && sub->update == SM_UPDATE_NONE)) {

in that patch.
