If you have an existing HTML archive and the corresponding .mbox, and
you run bin/arch without --wipe, every message in the mbox will be added
to the HTML archive, but they won't be indexed because the Message-IDs
are duplicates.

For example if there are a total of 10 messages in the archive, the HTML
messages will have names like 000000.html, 000001.html, ...,
000009.html. If you then run bin/arch without --wipe, you will add files
000010.html, 000011,html, ..., 000019.html which may or may not be a bit
different if you modified the mbox. Now, when the archiver added say
000010.html, its Message-ID is the same as that of 000000.html, so it
won't be indexed and the index will still point to 000000.html.

The answer is if you want to rebuild and archive and not just add to it,
you have to use --wipe to remove the existing HTML archive before adding.
