Hi, Mark.  Thanks so much for working on this.  This new solution seems
like a good one.  It keeps the default as expected (excluded are
actually excluded from all output), and the with-excluded option behaves
intuitively.  Looks good to me.

Unfortunately, as I discussed with you on irc today, there seems to be a
problem with the patch series that is preventing it from working as
expected.  The outputs of the following commands should agree, which
they do:

servo:~/src/notmuch/git [master] 0$ ./notmuch count --with-excluded tag:inbox
51171
servo:~/src/notmuch/git [master] 0$ ./notmuch search --output=messages --with-excluded tag:inbox | wc -l
51171
servo:~/src/notmuch/git [master] 0$ 

However, they should also agree in this case, which they don't:

servo:~/src/notmuch/git [master] 0$ ./notmuch count tag:inbox
115
servo:~/src/notmuch/git [master] 0$ ./notmuch search --output=messages tag:inbox | wc -l
51169
servo:~/src/notmuch/git [master] 0$ 

In this last case, notmuch search is outputting (some but not all(!))
excluded messages when it shouldn't be.  However, if I use a more
complicated search term, everything seems to be working fine:

servo:~/src/notmuch/git [master] 0$ ./notmuch count tag:inbox and tag:unread
0
servo:~/src/notmuch/git [master] 0$ ./notmuch search --output=messages tag:inbox and tag:unread | wc -l
0
servo:~/src/notmuch/git [master] 0$ ./notmuch count --with-excluded tag:inbox and tag:unread
47245
servo:~/src/notmuch/git [master] 0$ ./notmuch search --output=messages --with-excluded tag:inbox and tag:unread | wc -l
47245
servo:~/src/notmuch/git [master] 0$ 

It also works if I give a single "from:" search term instead of a single
"tag:" search term.  So it appears to be something about how the
excluded query is constructed.

I can't figure out where the problem is, although I'm still looking.  If
anyone else can figure it out, please let us know.

I would really like to get this series applied so that I can get back to
following master!

Thanks again for all the work.

jamie.
