Sure, I can clean up the wording.

This was from an email issue I should have handled better. For some
reason, send-email hit an error with smtp after sending the cover
letter and failed to send the rest. When I then sent the rest
separately, I failed to consider the threading and didn't think to use
the option to force it to work as a reply to an ID from the already
sent cover letter.
