If there's no material change between the old and new default lists, we would typically leave the old one along, even if there is some issue with whitespace or misspelled comments or other "cosmetic" problem. If the old lines are shorter than 80 chars, then we should switch back to the old ones to avoid an unnecessary diff in the pull request. If the old lines are > 80 chars, then this is probably an ok time to fix that. Checking...only Brazilian Portuguese extends past 80 chars, so that criterion is somewhat ambivalent.
