Notice that after reorganizing the tab handling my layout becomes really simple:

  set hidden diffopt-=hiddenoff | silent execute 'bufdo diffthis' | 4b

And your layout becomes:

  set hidden diffopt-=hiddenoff | echo | leftabove vertical split | 2b
| wincmd l | 1b | execute 'windo diffthis' | tabnew | leftabove
vertical split | 2b | wincmd l | 3b | execute 'windo diffthis'

So this "works" too, right?

Cheers.
