Would instead (run-hooks...) in the above, embedding:

    (let ((message-send-mail-function (lambda () t))
          (mail-host-address \"example.com\"))
and
     (notmuch-mua-send)

work (that is what we do in emacs_fcc_message () in test-lib.sh

?

You probably had tabs and spaces "correct" last time, but I got confused by
the extra line and forgot to drop indentation to see better. To be
consistent with other rests these lines do need to have tabs (width 8) and
rest spaces

I'd still do something like:

 test_expect_equal "$(notmuch search --output=tags id:$message_id)" \
 	$'forwarded\ninbox\nunread\n' 

(note: quoting aroung first arg and $'dollar-single' in second, but did not
test that this is what exactly works (newlines could be clearer, though) :)

... to ensure (and show visibility) that just "forwarded" were added. if
anyone(tm) ever changes system so that default tags change, many other
tests also need updating...
