For me is pretty useful because I use the iterator as a cursor on an ncurses
notmuch interface. So the selected thread is where the iterator is and the user
can to go forward or backwards.

:) Happy to see there is someone else needing it.

/me raises arm. Real use case here! Personally, I don't need the
backwards operator (and I don't see the case where I would need to go
back very often). But a _move_to_first() for threads, messages (and
probably tags), would be really useful to me now:

Having bound notmuch.so to python, I am in a situation, where I can only
offer iteration once, with subsequent iterations failing. This is very
unexpected and very un-pythonesque. I fell myself over it:

#the below len() iterates and exhausts msgs
if len(msgs) > 0:
   for msg in msgs: print msg
   #above line fails horribly already...
else: print "No message for me!"

So, having a way to reset the iterator would be a real boon already now.

[notmuch] reverse iterators

[Ruben Pollan]

Adds support to reverse iteration on messages, threads and tags. To revew and
think if makes sense to include them on notmuch or wait until they have a real
use.

The patch 3 "Move the logic of threads iterator out of 'valid'" is just a 
reorganization of the code, I think it makes sense to include it in notmuch even
if we decide that the reverse iterators are not included.
