Subject: bug#4657: 23.1.50; duplicate entries in file-name-history from read-file-name
Date: Wed, 07 Oct 2009 00:26:39 +0200

In a fresh emacs -q load and execute the command foo in order to
read the file name ~/foo/bar

(defun foo ()
  (interactive)
  (read-file-name "File: (default ~/foo/bar) " "~/foo/" "~/foo/bar")
  (message "%s" file-name-history))

If I explicitly enter ~/foo/bar in the minibuffer, multiple
executions of this command add this file to file-name-history only
once. If I am lazy and just use the default value, each execution
will add one more entry ~/foo/bar to file-name-history. I would
expect that multiple equal entries in succession should always be
avoided in file-name-history.
