;;; 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
;; For 0.8:
;; - Fix display of unmerged files.
;; - Fix performance problems with large status buffers.
;; - Handle the case where remote and local branches have different names.
;; Later:
;; - Queuing of asynchronous commands.
;; - Good email integration.
;; - Showing tags.
;; - Visiting from staged hunks doesn't always work since the line
;; numbers don't refer to the working tree. Fix that somehow.
;; - Figure out how to discard staged changes for files that also have
;; unstaged changes.
;; - Get current defun from removed lines in a diff
;; - Amending commits other than HEAD.
;; - 'Subsetting', only looking at a subset of all files.
