[MlMt] How can I copy the Markdown of a message I wrote earlier?

[leo]

Hi all,

Sometimes I want to reuse parts of a message I wrote in Markdown in a 
new Markdown message. For this it would be handy to copy the Markdown 
source of the old message. Where can I get this text?

(I can see in the raw view that the Markdown version is stored in the 
message, but in the raw view it is encode d an escaped in a way that it 
is pretty useless to copy it out.)

Thanks,
Leo
