Conversion appends a new line which is always unix style

[blaisejarrett]

When converting a file the tool seems to append a new line to the end of the file under certain conditions - Not sure what conditions.

When it appends a new line it seems to always append a "\n" unix style new line. Even when the rest of the file may have different line endings.

1. Does the tool have to append a newline? If so.
2. Can the output file have consistent line endings that ideally match the sources line endings?

Before source:

from PySide import QtGui
if __name__ == '__main__':
    QtGui.QApplication([])

Before source as Hex:

Source after:

from Qt import QtWidgets
if __name__ == '__main__':
    QtWidgets.QApplication([])

00000050: 285b 5d29 0a                             ([]).

Note the 0a \n newline at the end of the file even though the file previously contained 0d0a \r\n windows style newlines.

Looks like the underlying redbaron ast is adding this.

I will see if I can disable this. If not, I will filter line endings before I output the result and make sure they all conform.
