Statusline integration does not respect "rotate" option

[schreifels]

First of all, thank you for this plugin! I have found it to be really useful. Recently, I came across this issue:

It seems that the "rotate" option only works with command bar mode. If I use these settings:

let g:bufferline_show_bufnr = 0
let g:bufferline_rotate = 2
let g:bufferline_echo = 0
autocmd VimEnter *
  \ let &statusline='%{bufferline#refresh_status()}'
  \ .bufferline#get_status_string()

I get behavior like this:

All good, current buffer highlighted

But when the current buffer is changed, the statusline does not scroll

If I comment out the last three lines of that config, I see:

Current tab is highlighted

Switch to a neighboring buffer, and bufferline scrolls as expected

vim 7.4
vim-bufferline 706e059

Any thoughts would be greatly appreciated. Thanks!
