[PATCH] emacs: hello: display jump key next to saved search when available

[Jani Nikula]

Display the shortcut jump key next to the saved search name in notmuch
hello, if one is defined for the saved search.

---

This is probably something with infinite bikeshedding
potential. Therefore I just quickly hacked something together as a
proof of concept. This displays the jump keys like this:

	154 Inbox [j i]

Maybe the space between "j" and the key is unnecessary? Maybe the "j"
itself is unnecessary? Maybe the brackets are unnecessary? Maybe it
could use some color? Does displaying these need to be customizable?
Etc?
