[notmuch] Snippet to jump to message in Gnus from notmuch-show buffer

[Brett Viren]

Hi Tassilo,

I adapted your code for my use and found it was failing due to some
stray double-quotes.  I'm using notmuch from git so maybe these quotes
were added in the year since you first posted your idea.

See below for the simple fix:

I needed to define the message-id like:

       (message-id (replace-regexp-in-string
		    "\"" ""
		    (replace-regexp-in-string
                    "^id:" "" (notmuch-show-get-message-id)))))

>        (org-gnus-follow-link group message-id)
>      (message "Couldn't get relevant infos for switching to Gnus."))))

Regards and thanks for this handy code!
