upgrade or reshard Xapian DB(s) used by public-inbox
options:
--compact | -c run public-inbox-compact(1) after indexing
--all copy all configured inboxes
--reshard=NUM change number the number of shards
--jobs=NUM limit parallelism to JOBS count
--verbose | -v increase verbosity (may be repeated)
--sequential-shard copy+index Xapian shards sequentially (for slow HDD)
index options (see public-inbox-index(1) man page for full description):
--no-fsync speed up indexing, risk corruption on power outage
--batch-size=BYTES flush changes to OS after a given number of bytes
--max-size=BYTES do not index messages larger than the given size
See public-inbox-xcpdb(1) man page for full documentation.
