Then referrer reports will only go back as far as the data does. Analog doesn't
process error reports (they're meant for human consumption).

Again, does not affect the cache files.

The only things that affect cache files are inclusions and exclusions (including
those implied by time commands [FROM and TO] and *LOWMEM commands and those
created by changes in logformat). If the data in a cache file is changed, Analog
would still run, but some values may be erroneous (e.g. total count for
previously excluded file, host, browser, etc) and some reports may not have data
as far back as others (e.g. adding referrer data).
