Re: wdired-change-to-wdired-mode needs a key binding in dired-mode

`C-x C-q' has one bad effect.  I sometimes type `C-x C-q' in the *Locate*
buffer to remove unnecessary lines with `flush-lines' and `keep-lines'
(to narrow down usually huge result list).  But now when I type `C-x C-q'
in *Locate* it raises the error:

Debugger entered--Lisp error: (error "Not a Dired buffer")
  signal(error ("Not a Dired buffer"))
  error("Not a Dired buffer")
  wdired-change-to-wdired-mode()
  call-interactively(wdired-change-to-wdired-mode)

Since wdired doesn't work in modes that inherit from dired-mode,
it would be useful to leave the original binding to toggle-read-only
in them:
