Comment 5 for bug 1094788

It appears vim-sparkup is the issue. Once I added vim-sparkup to the minimal `.vimrc` the issues reappeared.

```
set nocompatible
set tabstop=2 expandtab softtabstop=2 shiftwidth=2

set rtp+=/Users/smckinney/.vim/bundle/supertab
set rtp+=/Users/smckinney/.vim/bundle/ultisnips
set rtp+=/Users/smckinney/.vim/bundle/vim-sparkup

syntax on
filetype plugin indent on
```

Output of `:verbose imap <tab>`:

```
i <Tab> * <C-R>=UltiSnips_ExpandSnippet()<CR>
Last set from ~/.vimfiles/vim/bundle/ultisnips/plugin/UltiSnips.vim
```
