;;; Commentary
;; Invoking the magit-status function will show a buffer with the
;; status of the current git repository and its working tree. That
;; buffer offers key bindings for manipulating the status in simple
;; ways.
;; The status buffer mainly shows the difference between the working
;; tree and the index, and the difference between the index and the
;; current HEAD. You can add individual hunks from the working tree
;; to the index, and you can commit the index.
;; See the Magit User Manual for more information.
;;; TODO
;; - Showing tags
;; - Amending commits other than HEAD.
;; - Visiting from staged hunks doesn't always work since the line
;; numbers don't refer to the working tree. Fix that somehow.
;; - Get current defun from removed lines in a diff
;; - Equivalent of git-wtf,
;; - 'Subsetting', only looking at a subset of all files.
;; - Untracked directories should show one entry, not all contents
;; - `n' and `p' at the end of the status buffer shouldn't error
