dired-jump

[Miles Bader]

I just found out about a very very handy binding (thanks to David
Kastrup's comment on another mailing list): C-x C-j  -- dired-jump
(which when given in a file buffer, pops up a dired  buffer on its
directory with point positioned over the entry for that file).

Unfortunately this only gets bound if you load dired-x.el.

This seems so handy that I think it really ought to be bound by default
(`dired-jump' is already autoloaded from dired-x.el) -- having global
non-mode-specific bindings take effect only when you load a particular
lisp file seems most peculiar when that file is part of the standard
lisp distribution.

The code which binds dired-jump to `C-x C-j' is conditional upon the
variable `dired-bind-jump' -- if that variable is nil, then the binding
is not done.

We could simply continue honoring `dired-bind-jump', but move the
binding code from dired-x.el to bindings.el (and maybe add a bit of
customize magic to make changes to `dired-bind-jump' do something
intelligent).  [If bindings.el is executed before dumping, perhaps this
code would need to be put somewhere that happens after loading the
user's init file...]

Here's the code from dired-x.el:

   ;;; GLOBAL BINDING.
   (if dired-bind-jump
       (progn
         (define-key global-map "\C-x\C-j" 'dired-jump)
         (define-key global-map "\C-x4\C-j" 'dired-jump-other-window)))


What do people think?
