Might create blank line at start of file with comments

[blueyed]

Running isort --diff with the following will add a blank line at the start:

# comment
import os
# comment2
import sys

@@ -1,4 +1,5 @@
+
+import os
 # comment
-import os
 # comment2
 import sys

The result then looks like this:

import os
# comment
# comment2
import sys

Thank you for reporting this!
Should be fixed in the latest release (4.3.13) of isort.

Thanks!
