I think we can put the test that this patch adds to do_xlate_actions()
in xlate_actions() instead, adding it as another clause (probably via
helper function?) in the same 'if' statement as the may_receive() test.
That's preferable because we'd only do it one time per translation
instead of once per resubmit.
The outer () is not needed here:
