In 2.1.10 (released April last year) a new Sibling List feature was
added which will handle this.  The changelog reports:

"Added a new 'sibling list' feature to exclude members of
another list from receiving a post from this list if the
other list is in the To: or Cc: of the post or to include
members of the other list if that list is not in the To: or
Cc: of the post (Patch ID 1347962)."

From the web admin gui, it's under 'Non-digest options' where you will
see two options:

* Other mailing lists on this site whose members are excluded from the
regular (non-digest) delivery if those list addresses appear in To: or
Cc: header.

* Other mailing lists on this site whose members are included in the
regular (non-digest) delivery if those list addresses don't appear in
To: or Cc: header.

It's quite easy to add as a patch to earlier versions if you need to (I
added it to 2.1.9 quite recently).
