error: void-variable cl-struct-tramp-file-name-tags

[William Xu]

When in *shell* mode, 

,----[ *shell* ]
| think-different:~$ cd /
`----

followed by a TAB will causes this error. The backtace is, 

,----[ backtrace ]

I found that if i disabled ido config, it has no such problem. My ido
config is: 

,----[ ido config ]
| (setq ido-create-new-buffer 'never
|       ido-enable-regexp t)
| 
| (setq ido-ignore-buffers
|       '("\\*.+\\*" ".diary"))
| 
| (ido-mode 1)
| (ido-everywhere 1)
`----

The weird thing is that if i disable ido config when starting emacs, but
eval them manually after emacs started, this error doesn't throw.
