I think notmuch_bool_t will be better than int here.

BTW what is the reason for using notmuch_bool_t instead of bool from
stdbool.h?

Again, notmuch_bool_t is IMHO better. You seem only to use values -1 and
1 which is quite confusing.

You might also want to set this to FALSE somewhere. It is very unlikely,
but somebody can create non-maildir under maildir.

You add the tags only to newly discovered mails. If a file is renamed
(e.g. because another mail reader removed the S flag), the tags will not
be updated. It is a question, what is the proper behavior. I personally
use something like what is in your patch and then use notmuchsync to
handle renamed files. It has only one problem - notmuchsync is quite
slow, so if this is solved in notmuch, I'd be happy.

Cheers,
 Michal
