refactor(users/glittershark): Rename to grfn r/2485

Rename my //users directory and all places that refer to glittershark to
grfn, including nix references and documentation.

This may require some extra attention inside of gerrit's database after
it lands to allow me to actually push things.

+;;; Commentary:

+;; Provides the google C/C++ coding style. You may wish to add
+;; `google-set-c-style' to your `c-mode-common-hook' after requiring this
+;; file. For example:
+;;
+;;    (add-hook 'c-mode-common-hook 'google-set-c-style)
+;;
+;; If you want the RETURN key to go to the next line and space over
+;; to the right place, add this to your .emacs right after the load-file:
+;;
+;;    (add-hook 'c-mode-common-hook 'google-make-newline-indent)
+
+;;; Code:
+
+;; For some reason 1) c-backward-syntactic-ws is a macro and 2)  under Emacs 22
+;; bytecode cannot call (unexpanded) macros at run time:
+(eval-when-compile (require 'cc-defs))
+
+;; Wrapper function needed for Emacs 21 and XEmacs (Emacs 22 offers the more
+;; elegant solution of composing a list of lineup functions or quantities with
+;; operators such as "add")
