Git status shortcuts broken edge case: moved file

[LeZuse]

To reproduce simply move a checked in file from a previous commit and stage it. Git detects a moved file:

$ git status
# On branch: master  |  [*] => $e
#
➤ Changes to be committed
#
#        renamed: [1] "app.js -> app2.js"

$e1 now contains invalid filename:

$ echo $e1
/Users/zuse/Projects/pb-frontend/apps/main/"app.js -> app2.js"

$ git --version
git version 2.10.2
$ cd ~/.scm_breeze/
$ git show --oneline

I fixing this by reverting for now. We need better test coverage to handle a major change like the refactorization that was merged in #262
