For what it's worth, I took a simple test message, saved it into a new mailbox, and then used vi to make four copies of the message. I removed the Content-Length: and Lines: header lines from all four copies, and the trailing blank line from two of the copies. When I opened up this mbox file using "mutt -f" and saved each message to a new mailbox (in various orders), I found that the presence-or-not of a trailing blank line was preserved in the copies. I got the same results from these tests with both with a "current" version of mutt, v1.5.21 from the Ubuntu Precise package, and a "very old" one, v1.5.9i from the Debian Sarge package. So... it does appear that Mutt will preserve whatever trailing-blank- line situation was originally created by the MDA, even as it saves the messages into new mailboxes (and that it doesn't actually care what convention was used by other messages previously found in the mailbox being appended to).
