failed to change from unread to read

[Ian Kelling]

I was reading a thread I got to from a folder: search, and in the thread
was a message from a different maildir folder, and notmuch would not
mark it as read like it did with normal messages. That one would just
remain unread when I hit space on it. Not the right behavior imo.

I've had generally good first impression of notmuch, but with the
glitches, I'm going back to gnus now now.
