Comment:

 17904.4.patch is a refreshed version of the patch to r33083 + some
 adjustments :

 - If i understand well, these characters `_ - @ .` are now allowed for the
 user login, so i've removed the `contains_underscores` index from the
 dataset of  `Tests_Multisite_WpmuValidateUserSignup->test_user_name`
 - When a user signups with a blog, i suggest to make sure the  `_ - @ .`
 characters are removed from the `blogname` input in `show_blog_form()` as
 the user_name is used as the default value of the blog's name.
