;;; Commentary:

;; This file set up `magic-mode-alist' so that Emacs recognizes a
;; number of file types based on the content.
;;
;; This is especially useful when using `less' in pipes, in which case
;; Emacs can't pick a suitable major mode based in a file name.

;;; Code:

(defun e2ansi-magic-diff-p ()
  "Return non-nil if the content of the current buffer looks like a diff."
  ;; This is the format used by "svn diff".
  (re-search-forward "^@@ " magic-mode-regexp-match-limit t))

(add-to-list 'magic-mode-alist
             '(e2ansi-magic-diff-p . diff-mode))
