bug#25423: 25.1; Can't use dired with spaces or special characters in folder names using tramp

[Alex Branham]

I can't navigate (or do anything else like dired-do-chmod) using dired when 
directories have spaces or special characters over a tramp connection. I think 
it's because Emacs is putting quotes '' or "" around the folders in question.

Using `emacs -Q` and navigate to a directory like below. I can hit RET to go to 
Folder1 but neither 'Folder 2' nor "Folder's 4". Note that the folders don't 
actually have quotation marks in their name --- Emacs is adding that in the 
dired buffer. 

  drwxrwsr-x  3 owner group 4096 Jan  9 19:29  Folder1
  drwxrwsr-x  3 owner group 4096 Jan  9 20:47 'Folder 2'
  drwxrwsr-x  3 owner group 4096 Jan  9 19:30 "Folder's_3"
