Solution for "Buffer named *helm* not found" issue on invoking emacsclient

emacsclient.el

;;; Handle *helm* buffer not found issue 2014-09-24
;; It is caused by helm--maybe-update-keymap remaining in post-command-hook.
;; helm--maybe-update-keymap requires *helm* to be present.
;; It should be remove-hook'ed, but it does not happen when doing *.Rnw editing.
;; The main problem is emacsclient hits this error and die.
;; Magit uses emacsclient for COMMIT messages, so it does not work.
;;
;; Define a function to remove helm--maybe-update-keymap from post-command-hook
(defun remove-helm--maybe-update-keymap ()
  (remove-hook 'post-command-hook 'helm--maybe-update-keymap))
;;
;; This function should be called before helm--maybe-update-keymap is used.
;;
;; Candidate hooks for making this happen.
;; server-done-hook	Hook run when done editing a buffer for the Emacs server.
;; server-mode-hook	Hook run after entering or leaving `server-mode'.
;; server-switch-hook	Hook run when switching to a buffer for the Emacs server.
;; server-visit-hook	Hook run when visiting a file for the Emacs server.
