Done.

Indeed, IMHO the python bindings are perfect for this sort of
application.

The watch tag is one of the defining points of my workflow. I deal with
a lot of lists although generally I'm interested in very few threads
from each. The watch tag makes it very easy to find and follow relevant
discussions.

Just to make sure everyone understands what is happening here, the
workflow works as follows,

 1) When a message starting a new thread is encountered it is marked as
    "unseen"

 2) I look at the "unseen" tag, marking threads of interest with "watch"

 3) When a message comes in associated with an existing thread marked
    with "watch" it is marked with "inbox", otherwise it is ignored

In other words, the "unseen" tag is an indicator of whether I have
evaluated the message for interest. I use the standard "unread" tag to
mark whether I have read the contents of the message.

Doh, thanks for pointing that out. Your tag_search implementation
matches mine almost verbatim. For the record I have included
notmuch_utils.py below.

Good point. Thanks!
