Emacs interface (notmuch.el)

+Make hidden components self documenting, such as:

+ [24-line citation, press 'c' to display.]
+
Add support to compose a reply to the current messaage.
notmuch command-line tool
-------------------------
+Give "notmuch restore" some progress indicator. Until we get the
+Xapian bugs fixed that are making this operation slow, we really need
+to let the user know that things are still moving.
+
Make "notmuch setup" not index all messages, but only what it can do
in a reasonable amount of time, (then add "notmuch index" so the user
can complete the job when convenient).
