There appears to be some cases of duplicates appearing due to
-extindex. I haven't nailed down the cause of it, yet, but
this should make things easier for readers using the PSGI
HTML interface in the meantime.
The raw mboxrd remains undeduplicated for now, and the
correct fix/workaround would be some fsck-like mode for
public-inbox-extindex.
