encoding when forwarding messages

[Eric Abrahamsen]

I saw another message about the same problem on this list, in January,
with the advice to upgrade to git, but I'm still seeing it on notmuch
0.16+7~gdc51bf0. Forwarding a message from within emacs using
`notmuch-mua-forward-message' sometimes produces garbled encoding.
Calling `notmuch-show-forward-message' on the same message, however,
creates what appears to be a raw message, properly encoded.

Is there something still amiss in the code? Am I using the wrong
command?

Thanks!
Eric
