TODO: Remove many items that have been completed recently.

There's been a lot of good work done, and we've been doing a generally
poor job of noticing when some of the tasks we've completed were
already on our TODO list.

So here's a careful scan, removing all items I could find that have
already been done.

-Fix defect #250

-	replace_document should make minimal changes to database file
-	http://trac.xapian.org/ticket/250
-
-	It looks like it's going to be easy to fix. Here's the file to
-	change:
-
-		xapian-core/backends/flint/flint_database.cc
-
-	And look for:
-
-	  // FIXME - in the case where there is overlap between the new
-	  // termlist and the old termlist, it would be better to compare the
-	  // two lists, and make the minimum set of modifications required.
-	  // This would lead to smaller changesets for replication, and
-	  // probably be faster overall
-
-	So I think this might be as easy as just walking over two
-	sorted lists looking for differences.
-
-	Note that this is in the currently default "flint" backend,
-	but the Xapian folks are probably more interested in fixing
-	the in-development "chert" backend. So the patch to get
-	upstreamed there will probably also fix:
-
-		xapian-core/backends/chert/chert_database.cc
-
-	(I'm hoping the fix will be the same---an identical comment
-	exists there.)
-
-	Also, if you want to experiment with the chert backend,
-	compile current Xapian source and run notmuch with
-	XAPIAN_PREFER_CHERT=1. I haven't tried that yet, but there are
-	claims that a chert database can be 40% smaller than an
-	equivalent flint database.
