Currently as both setting notmuch-address-command and
notmuch-address-message-insinunate us required I would not attempt to do any
"magic" there. Whenever we get built-in address completion (i.e built-in
is used when notmuch-address-command is kept nil we could consider to add
some defcustom which can be used to activate address completion -- but 
as there are these *-insinunate -commands in many elisp packages it is
probably best to investigate whether this really can be "automated".
Perhaps some lazy initialization could be in place, then.

That is interesting in a sense that I could not reproduce. I think I know
exactly why this happens: notmuch-view-raw-message creates read-only buffer
which is not removed after message is resent: re-running
notmuch-view-raw-message on same message will `get-buffer-create' with
same name and pick the old read-only buffer; inserting data to that buffer
fails -- just that in my tests (V C-x b RET V) I could not get the same
outcome.

The simplest change is to change (bury-buffer) with (kill-buffer). The raw
message buffer that was used to send should not be interesting; more
interesting is the current (same) message in notmuch-show buffer -- and 'V'
can be used to re-view the raw message. 
What could be added is printing the message id of the message resent to
*Messages* buffer. This way re-sender can verify what was resent if being
unsure. Just that in the case I've used this I have not looked back...

So, probably I make applicable RFC patch of this feature...
