i'd like to replace this code snippet in /etc/rc with the
one distributed with nvi:


virecovery=`echo /var/tmp/vi.recover/recover.*`
if [ "$virecovery" != "/var/tmp/vi.recover/recover.*" ]; then
        echo preserving editor files
        for i in $virecovery; do
                sendmail -t < $i
        done
fi


with the below script (from src/usr.bin/vi/recover/recover.script)
either embeded in /etc/rc, or as a separate file (i don't care).

it adds these features:

	- get rid of certain non-recover files
		- non readable backup files
		- non readable recover files
		- unmodified backup files
	- only send mail about files that have a valid
	  X-vi-recover-path: header, deleting others.


i'm tempted to feel that we should delete the recover files after
they have been mailed once in any case so that the user is not
sent multiple messages.


comments?
