SUMMARY

Code is duplicated when formatting Python source with the last line not being empty


STEPS TO REPRODUCE
1. create a file with content `print ()\na = 1` (where \n stands for a newline) NOTE: no trailing newline, the file should contain exactly those two lines and no empty one at the end
2. run format (Ctrl+T,F by default)
3. the file is now `a = 1\nprint ()\na = 1` instead of `print()\na = 1\n`

OBSERVED RESULT

Not formatted and with a line having been duplicated:
`a = 1\nprint ()\na = 1`

EXPECTED RESULT

formatted and no duplicate:
`print()\na = 1\n`
