Most cases of these iterators are built on Xapian iterators, (C++ objects with
overloaded operators). So those are just using ++ for advance() and can
easily use -- for the new function, (I'd like a verb that pairs better
with "advance" than the non-verb "back"---any suggestions)?
So those won't need any new code. The one case that will need new code
is that for notmuch_message_get_replies and
notmuch_message_get_toplevel_messages the messages iterator is currently
built on a singly-linked list. Making it doubly linked would obviously
not be hard though.
