Actually you should only have to run expire -R (upper case).  This will
just rebuild the dbm copy of the history file from the text version and
is a lot faster.

The -r option will have to scan the entire set of news articles, parse
each file, and sort the output by date.  Depending on the amount of news
you keep this can take many hours.

And, of course, you can delete the 0-9 files.
