v2: support incremental indexing + purge

This is important for people running mirrors via "git fetch",
as they need to be kept up-to-date.  Purging is also now
supported in mirrors.

The short-lived "--regenerate" option is gone and is now
implicitly enabled as a result.  It's still cheap when
article number regeneration is unnecessary, as we track
the range for each git repository.
