git-blame: Add Emacs Lisp file headers and GNU GPL boilerplate
Add Emacs Lisp file headers, according to "Coding Conventions" chapter in Emacs Lisp Reference Manual and Elisp Area Convetions for EmacsWiki: Those include: copyright notice, GNU GPL boilerplate, description and instalation instructions as provided in email and in commit message introducing git-blame.el, compatibility notes from another email by David Kågedal about what to change to use it in GNU Emacs 20, and "git-blame ends here" to detect if file was truncated. First line includes setting file encoding via first line local variable values (file variables). Added comment to "(require 'cl)" to note why it is needed; "Coding Conventions" advises to avoid require the `cl' package of Common Lisp extensions at run time.

+;;; Commentary:
+;; Here is an Emacs implementation of incremental git-blame. When you
+;; turn it on while viewing a file, the editor buffer will be updated by
+;; setting the background of individual lines to a color that reflects
+;; which commit it comes from. And when you move around the buffer, a
+;; one-line summary will be shown in the echo area.
+;;; Installation:
+;; 1) Load into emacs: M-x load-file RET git-blame.el RET
+;; 2) Open a git-controlled file
+;; 3) Blame: M-x git-blame-mode
+;;; Compatibility:
+;; It requires GNU Emacs 21. If you'are using Emacs 20, try
+;; changing this:
+;; (overlay-put ovl 'face (list :background
+;; (cdr (assq 'color (cddddr info)))))
+;; to
+;; (overlay-put ovl 'face (cons 'background-color
+;; (cdr (assq 'color (cddddr info)))))
