I encountered another problem:

  Using `C-c C-k' in the remember buffer is OK.

  But if the user interupts `org-remember' by `C-g' (e.g. when reading
  some text interactively), emacsclient will be waiting for ever.


Unfortunately, there seems no easy way to fix this in a way, that we
could mix org-protocol arguments and filenames for emacsclient.

A solution for this problem is, to introduce a new property:


(defconst org-protocol-protocol-alist-default
  '(("org-remember"    :protocol "remember"    :function org-protocol-remember :kill-client t)
...

and unconditionally kill the client, once a sub-protocol with a non-nil
`:kill-client'  property is detected.



The appended patch does all the changes we need:

    - call org-remember the right way
    - kill emacsclient for org-protocol-remember and all those handlers,
      which have the `:kill-client' property set to a non-nil value.
