Re: backup method

[Richard Stallman <rms@gnu.org>]

    My prove is:

      unset TMP TMPDIR
      export VISUAL='emacs -q' # which does backup by moving by default
      crontab -e

    And you can edit your crontab fine since emacs won't make a backup
    of files in /tmp

So you're not editing the crontab files under their real names, but
rather, editing copies that were made in /tmp?

If so, I understand the situation now.  Thanks.  Does this fix it?
