Re: What happened to wdired.el?

[Richard Stallman]

    wdired provides one user-level function `wdired-change-to-wdired-mode'
    to start editing the file names and two functions to exit wdired-mode:
    `wdired-finish-edit' and `wdired-abort-changes' with the former
    committing the changes and the latter aborting them.  Both return
    wdired to dired mode.

I think that is the right way to do it.
The Rmail Edit feature uses C-c C-c to finish the edit
and C-c C-] to abort.  It would be a good idea for wdired to
use the same bindings.  (Maybe it already does.)
