Pavel Holejsovsky 3d2321b317 Make async git invocation work on cygwin. 
Forces emacs to use pipes for communication with git subprocess.
Although default PTY method should work too, there is probably
something broken in cygwin causing that resulting process never
receives any input and hangs forever.

In any case, setting communication to 'pipe' is recommended by
start-process docs anyway for background processes, as it is usually
faster and more efficient.

;;; 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.
