M-x shell<enter>
mkdir -p /tmp/A\ \&\ B/ABC<enter>
cd /tmp/A<tab>
cd /tmp/A\ \&\ B/ # auto-complete successful
cd /tmp/A\ \&\ B/A<tab> # cannot auto-complete to ABC

The following fixes the problem:
<enter>
exit<enter>
C-x k<enter>
C-x b
*scratch*
(setq
 shell-command-regexp
  "\\(?:\\(?:[\\][\\]\\)+\\\\[;&|
]\\|[^\\]\\\\[;&|
]\\|[^;&|
]\\)+"
  shell-command-separator-regexp
  "\\(?:\\(?:[\\][\\]\\)+[;&|
]\\|[^\\][;&|
]\\)*")

 (defun shell-forward-command (&optional arg)
   "Move forward across ARG shell command(s).  Does not cross lines.

   (interactive "p")
   (let ((limit (line-end-position)))
     (if (re-search-forward (concat shell-command-regexp

                 limit 'move arg)

    (setq limit (line-beginning-position)))
     (skip-syntax-backward " " limit)
     (if (re-search-backward
       (format "\\(?:\\(?:[\\][\\]\\)+[;&|]\\|[^\\][;&|]\\)+[\t ]*\\(%s\\)"

       limit 'move arg)
      (progn (goto-char (match-beginning 1))
