commit https://github.com/vim/vim/commit/015102e91e978a0bb42a14461c132a85e8f7e1ea Author: Bram Moolenaar <Bram@vim.org> Date: Sat Jul 16 18:24:56 2016 +0200 patch 7.4.2050 Problem: When using ":vimgrep" may end up with duplicate buffers. Solution: When adding an error list entry pass the buffer number if possible.

" Vim script used in test_eval.in.  Needed for script-local function.

func! s:Testje()
  return "foo"
endfunc
let Bar = function('s:Testje')
$put ='s:Testje exists: ' . exists('s:Testje')
$put ='func s:Testje exists: ' . exists('*s:Testje')
$put ='Bar exists: ' . exists('Bar')
$put ='func Bar exists: ' . exists('*Bar')
