Here's find-file-read-args:
(defun find-file-read-args (prompt mustmatch)
(list (let ((find-file-default
(and buffer-file-name
(abbreviate-file-name buffer-file-name))))
(minibuffer-with-setup-hook
(lambda () (setq minibuffer-default find-file-default))
(read-file-name prompt nil default-directory mustmatch)))
t))
Here's what it should be, so that `M-n' with `C-x C-f' gives you the file of
the cursor in Dired mode:
(defun find-file-read-args (prompt mustmatch)
(list (let ((find-file-default
(if (eq major-mode 'dired-mode)
(abbreviate-file-name (dired-get-file-for-visit))
(and buffer-file-name (abbreviate-file-name
buffer-file-name)))))
(minibuffer-with-setup-hook
(lambda () (setq minibuffer-default find-file-default))
(read-file-name prompt nil default-directory mustmatch)))
t))

That is a good feature. Would you please send a patch and change log
entry, and text for etc/NEWS?

`dired-get-file-for-visit' causes `C-x C-f' to fail when typed on
a non-file line in the dired buffer.

Good catch. How about one of these instead? I prefer the second; it's
simpler and quicker (`minibuffer-message' pauses).
;; This one gives you error feedback.
(defun find-file-read-args (prompt mustmatch)

(and this-file (abbreviate-file-name this-file)))

buffer-file-name)))))

Again, please post context diffs rather than just code,

Just use (dired-get-filename nil t).

Great; go for it.
(Were you aware of that simple solution when you reported the bug?)

No, sorry, while reporting a bug I wasn't sure something like this is better.
Later after looking at the error messages in the dired-get-file-for-visit
I realised that they are not necessary for the default value.
