C-x C-f RET change

[Florian Weimer]

In previous versions, C-x C-f RET reread the current buffer from the
disk.  In Emacs 22, it shows the the current directory using dired.
While the new behavior is certainly more intuitive for beginners, the
old behavior is needed more often by more advanced users, especially
if they are not yet so advanced that they do everything from within a
single Emacs process.

At the very least, the NEWS entry

| ** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case.
| 
| Since the default input is the current directory, this has the effect
| of specifying the current directory.  Normally that means to visit the
| directory with Dired.

should mention that the new key sequence is C-x C-f M-n RET.
