bug#11348: 24.0.95; TAB-completion in shell-command produces d:\/foo on MS-Windows

[Eli Zaretskii <eliz@gnu.org>]

 emacs -Q
 M-! cd d:\gnu TAB

(A directory 'd:/gnu' exists on my disk.)

After pressing the TAB key, the minibuffer displays this:

  cd d:\/gnu/

whereas the expected result is

  cd d:/gnu/

This is a regression from Emacs 23.4, where I do get "d:/gnu/".
