Spaces mistakenly interpreted as part of MyFamily line

In config.c in check_nickname_list() we have

  smartlist_split_string(sl, lst, ",",
    SPLIT_SKIP_SPACE|SPLIT_IGNORE_BLANK|SPLIT_STRIP_SPACE, 0);

Then in router.c in router_rebuild_descriptor() we have

    smartlist_split_string(family, options->MyFamily, ",",
      SPLIT_SKIP_SPACE|SPLIT_SKIP_SPACE|SPLIT_IGNORE_BLANK, 0);

Which one of these things is not like the other?

And do we have any other bugs like this?
