I think the only other place it's used is in getLog or something? I'm okay with that. Although that said I do have mixed feelings about having this commit in the php5 branch. For easier maintainability between the various branches and conflict avoidance I think it ought to be merged but if phpseclib didn't have a PHP4 branch at all then I'd say renaming login to _login and having login call _login would be unnecessary and could cause some limited confusion needlessly. idk lol
