* find-alternate-file from dired wildcard dir

find-alternate-file prompts with the current filename -- quite
helpful.  However if it is in a dired wildcard directory, e,g, from C-x d
*.c then this doesn't work.  The *.c isn't even available from M-n either.

Here's a workaround to make it available via `M-n':

(defadvice find-alternate-file (around dired-directory activate)
  "Use `dired-directory' as `buffer-file-name' when called interactively."
  (let ((buffer-file-name (and (interactive-p)
			       (stringp dired-directory)
			       dired-directory)))
    ad-do-it))

To automatically insert it in the minibuffer, you'd have to copy the entire
9-line `interactive' form from files.el to the advice and add the same
buffer-file-name binding to its `let' form as above.  But then you may as
well just modify files.el instead.

This doesn't handle the case where `dired-directory' is a list, which I
think only occurs when dired is called programmatically anyway.

Sorry, that breaks find-alternate-file outside of Dired buffers:

(defadvice find-alternate-file (around dired-directory activate)
  "In Dired, use `dired-directory' as `buffer-file-name' when called
interactively."
  (let ((buffer-file-name (if (and (interactive-p)
				   (eq major-mode 'dired-mode)
				   (stringp dired-directory))
			      dired-directory
			    buffer-file-name)))
    ad-do-it))

K> Sorry, that breaks find-alternate-file outside of Dired buffers:

Anyways, all the more argument for a set of keybindings that can
insert the current file, or current file name, or dired file on line name, or
recent-file-excluding-minibuffer-itself name, at point.  C-u for full
path.  Wouldn't that save hacking all the different places it is
needed?

It could be integrated with C-x r register stuff, but care should be
taken that the keystrokes don't get too long.

Here are some functions that can insert the current word, buffer name,
file name or directory name into the minibuf (as a bonus there is a 
function for selecting from minibuf history). I think, I already posted
it to emacs.sources, but anyway here it is.

Ehud.
