[feature request] emacs: use `notmuch insert` for FCC

[Steven Allen]

Instead of directly dropping messages into a maildir on FCC, it would be
better to pipe to `notmuch insert --folder=$dir -- $tags`. This way,

1. The message is indexed immediately and shows up in searches without
requiring a call to `notmuch new`.
2. It can be tagged.

(unless I'm missing something)

Unfortunately, I'm not comfortable enough with elisp to implement this myself.
