[patch] Wrong popup drawing in omni-complete.

[h_east]

Hi Bram and Vimmer,

How to reproduce:
- prepare foo.vim contents is below.
  set omnifunc=XXX
  set nowrap
  function! XXX(findstart, base)
      if a:findstart
          return col(".")
      endif
      normal! gg
      return ['aaa', 'bbb', 'ccc', 'ddd']
  endfunction

- start vim
  $ vim -N -u foo.vim

- input below.
  9o<Esc>o<C-X><C-O>


Expected behavior:
- Display popup on line 12.

Actual behavior:
- Popup Display two place.
  line 4 and line 12.
  line 4 popup is waste.

Attached a patch.
Please check this.

Thank you.
