While this is unlikely to be a problem in current practice,
keeping Xapian DBs open for long responses can interfere with
free space recovery after -compact.
In the future, it will interfere with inbox search grouping
and lead to unexpected results.

Some miscellaneous help and cleanup things, too.
Document data is no longer read from Xapian by read-only
daemons; that data is redundant given over.sqlite3 always
exists. This should should improve page cache hit rates for
over.sqlite3 by a small bit. Being able to mass load a bunch of
rows from SQLite speeds up the default search summary view by
~10%, too.
--skip-docdata option to -init and -index can avoid writing
Xapian document data, saving ~1.5% in Xapian space overhead
(and associated I/O and page cache overheads). It breaks
rollbacks to old versions, though, so it won't be the default.
Eric Wong (23):
doc: note -compact and -xcpdb are rarely used
admin: progress shows the inbox being indexed
compact: support --help/-? and perform lazy loading
init: support --help and -?
init: support --newsgroup option
init: drop -N alias for --skip-artnum
search: v2: ensure shards are numerically sorted
xapcmd: simplify {reindex} parameter passing
www: reduce long-lived PublicInbox::Search references
search: improve comments around constants
search: export mdocid subroutine
searchquery: split off from searchview
search: make qparse_new an internal function
smsg: reduce utf8::decode call sites
searchview: use over.sqlite3 instead of Xapian docdata
searchview: speed up search summary by ~10%
searchview: convert nested and Atom display to over.sqlite3
extmsg: avoid using Xapian docdata
mbox: avoid Xapian docdata in search results
smsg: remove from_mitem
t/nntpd-v2: set PI_TEST_VERSION=2 properly
init+index: support --skip-docdata for Xapian
search: add mset_to_artnums method
