Nvi saved the file "xxxxx"

[Mark <mdevin@ozemail.com.au>]

I keep on getting automatically emailed this message.  I have tried
doing vim -r which shows the following:
~$ vim -r
Swap files found:
   In current directory:
      -- none --
   In directory ~/tmp:
      -- none --
   In directory /var/tmp:
      -- none --
   In directory /tmp:
      -- none --

I have also searched the directory structure for such a file manually
and none exist.

Yet everytime I reboot my computer, I get another new email telling me
the following:
On Thu Apr 12 09:34:08 2001, the user mark was editing a file named
xxxxx on the machine debian, when it was saved for recovery. You can
recover most, if not all, of the changes to this file using the -r
option to vi:

How do I fix this?

Thanks.

Mark.
