How's it look now?
 can you squash this down to a single commit?
 Yeah, sure. Will I need to rebase on master too?
 does this close an issue?
 pls rebase this and can consider for 0.13.1
 @patricktokeeffe can you rebase and make that small change?
 OK @jreback I think I've finally succeeded without mucking up the repo. Let me know if it needs anything else. 
 @jorisvandenbossche ok on formatting?
 Just realized the issue # was missing from the commit log. It's been added & rebased over the last few commits. 
 OK!
 thanks
