Ok, some sillines in my part and something I did not check well
enough before replying...

First, notmuch-lib.el defines notmuch-send group, yet 
(defcustom notmuch-message-replied-tags ...) is defined 
in notmuch-message.el which is not requiring notmuch-lib...
and all of this works now...

Actually, notmuch-lib.el defines all defgroups (except coolj).

Then, I found the following: notmuch-mua-send-hook is defined 
both in notmuch-hooks and notmuch-send groups (having a precedent
helps a bit there when choosing alternatives below)


All the defgroups are defined using pattern:

(defgroup notmuch-<group> nil ...)

We should follow this pattern unless there is good reason not to 
do so here: notmuch-send is written as:

  (defgroup notmuch-send nil
    "Sending messages from Notmuch."
    :group 'notmuch)

  (custom-add-to-group 'notmuch-send 'message 'custom-group)

But, as the documentation in this notmuch-reply definition references
'Message insertion' group, doing

  (defgroup notmuch-reply 
    '((message-insertion custom-group))'
    "Replying to messages.

  Most of the reply customization settings can be found in `Message
  insertion' group. Notmuch specific settings are included directly
  here."
  :group 'notmuch)

could be good thing to do here; definition matches doc from the beginning
(just not adding any of the custom variables, yet).


Now, currently notmuch-message.el defines notmuch-message-replied-tags
and puts that to :group 'notmuch-send

There are 2 alternatives:

1) change that to :group 'notmuch-reply

2) add (custom-add-to-group 'notmuch-reply 'notmuch-message-replied-tags 'custom-variable)
   to notmuch-message.el (or notmuch-lib.el)

2b) change :group 'notmuch-send -> :group 'notmuch-reply and
   add (custom-add-to-group 'notmuch-send 'notmuch-message-replied-tags 'custom-variable)
   to notmuch-message.el (or notmuch-lib.el)


I personally would slightly lean to option 1 but if 2 gets more 
supporters then 2b (so that the spesific group is in the group definition).

On other words; 1 or 2b gets LGTM from me :)

Understood ? :D

Yes, I tested that missing group-thing with:

(defgroup foo '((bar-group custom-group)) "test")

It seems the nonexisting bar-group is created on-the-fly (but
exist temporarily). No warnings nor errors :).
