I thought about this too and this is why I checked for any
occurrence of Message-IDs in the other emails:

perhaps there was a logic error in how I did this:

   |> [2] grep -I "^Message-Id:" /tmp/thread-I-m-interested-in.mbox |sed -e "s/Message-Id: <//I" -e "s/>$//" >really.mid
   |>     grep -I -F really.mid rest.mbox
   |>     --> no match

/tmp/thread-I-m-interested-in.mbox  is a mbox with messages
I'minterested in, the "real" ones.  really.mid is a list of
Message-IDs of these "real" emails.  rest.mbox is a mbox with the
other emails, Emacs showed in his notmuch show buffer but are
other threads.

Since there is no match I concluded, the threads are not linked.
Perhaps I made a mistake.  I'l retest it and report again.  But
right now I don't have the time to do this.

Ciao, Gregor
