commit https://github.com/vim/vim/commit/3f188935ec4db5117c4a64cc3f71219175624745 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Aug 25 13:57:04 2015 +0200 patch 7.4.831 Problem: When expanding on the command line and encountering an error, the command is executed anyway. Solution: Bail out when an error is detected.

" 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')
