Visiting an image file fails on tty

[Juri Linkov]

In GNU Emacs 22.0.50 (i686-pc-linux-gnu) of 2006-08-28
after visiting an image file in tty-only built Emacs (i.e. no X),
it signals the following error:

Debugger entered--Lisp error: (void-function clear-image-cache)
  clear-image-cache()
  image-toggle-display()
  image-mode()
  set-auto-mode-0(image-mode nil)
  set-auto-mode()
  normal-mode(t)
  after-find-file(nil t)
  find-file-noselect-1(...)
  find-file-noselect(...)
  find-file(...)
  dired-advertised-find-file()
  call-interactively(dired-advertised-find-file)

But in the X no-toolkit version started in a tty with `-nw' option
the error is different:

Debugger entered--Lisp error: (error "Non-X frame used")
  clear-image-cache()
  image-toggle-display()
  image-mode()
  set-auto-mode-0(image-mode nil)
  set-auto-mode()
  normal-mode(t)
  after-find-file(nil t)
  find-file-noselect-1(...)
  find-file-noselect(...)
  find-file(...)
  dired-advertised-find-file()
  call-interactively(dired-advertised-find-file)

I think even if Emacs doesn't display images on a tty, it still makes
sense to open the content of an image file as text in the Emacs buffer
without an error.
