Iterating over one level of children requires parsing all snapshots

-    if (tree) {
-        char indentBuf[INDENT_BUFLEN];
-        char **parents = vshCalloc(ctl, sizeof(char *), actual);
+    if (!tree)
+        qsort(&names[0], actual, sizeof(char*), namesorter);

I had to rebase a bit here because of the bug fix in 40baa1c, but nothing too radical.


   Okay, getting parents global to the function as well as associated
cleanup looks a bit simpler actually.

Yeah, I was pleasantly surprised at how the function got easier to read even as it supported more fallbacks than before.
