patch 8.1.2060: "precedes" in 'listchars' not used properly Commit: https://github.com/vim/vim/commit/bffba7f7042f6082e75b42484b15f66087b01941 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Sep 20 17:00:17 2019 +0200 patch 8.1.2060: "precedes" in 'listchars' not used properly Problem: "precedes" in 'listchars' not used properly. Solution: Correctly handle the "precedes" char in list mode for long lines. (Christian Brabandt, closes #4953)

" Test if fnameescape is correct for special chars like !
func Test_fnameescape()
  let fname = 'Xspa ce'
  let status = v:false
  try
    exe "w! " . fnameescape(fname)
    let status = v:true
  endtry
  call assert_true(status, "Space")
  call delete(fname)

  let fname = 'Xemark!'
  let status = v:false
  try
    exe "w! " . fname->fnameescape()
    let status = v:true
  endtry
  call assert_true(status, "ExclamationMark")
  call delete(fname)
endfunc
