[PATCH] emacs: show/search: switch to caller/parent buffer when quit

[Tomi Ollila]

hello/search: in notmuch-hello-search-continuation switch (eventually)
call notmuch-hello with nil as no-display argument so that notmuch-hello
buffer is always switched to, instead of possibly to some other buffer
user may have visited in between.

show: added function `notmuch-show-quit` which switches to parent buffer
(of that is live) after killing current buffer. Otherwise control may
go to some other buffer user may have visited in between. This function
is now bound to "q" in notmuch-show-mode-map.
