I just added a -f|--filter-dupes flag to "b4 mbox" that will check the
existing maildir for existing duplicates before adding messages from the
retrieved thread. This allows neat things like retrieving the rest of the
thread directly from mutt. If you add the following to .muttrc:

macro index 4 "<pipe-message>~/bin/b4.sh mbox -f -o ~/Mail<return>"

(obviously, use something other than ~/Mail if it's not where your maildir is)

This lets you hit "4" in the index view to retrieve the rest of the thread for
the message that is currently selected (or tagged). Handy for when you're cc'd
in the middle of a discussion and want to grab everything else for context.

NOTE: -f requires iterating through the entire maildir to collect existing
msgids, so it's not recommended for huge maildirs.
