+Resend messages
+
+ The function `notmuch-show-resend-message` (bound to `b` in show
+ and tree modes) will (attempt to) send current message to new
+ recipients. The headers of the message won't be altered (e.g. `To:`
+ may point to yourself). New `Resent-To:`, `Resent-From:` and so on
+ will be added instead.
+
Face customization is easier
New faces `notmuch-tag-unread`, `notmuch-tag-flagged`,
