Changing of `mm-display-org-inline' may be postponed. I am curious 
however if there are a lot of users overriding their /etc/mime.types to 
avoid application/vnd.lotus-organizer.

However I am unsure whether `mm-uu-org-src-code-block-extract' is used 
to send messages. If it purpose to decode received messages then the 
change should be safe. I had a hope to receive some comments from 
developers familiar with Emacs mail clients.

I have realized that I missed `mm-automatic-display' there "text/org" 
should be added similar to `mm-inline-media-tests'.
