D6124: patch: include newline at EOF in help text for interactive patch

REVISION SUMMARY
  The lack of a newline means that some "editors" that are useful in
  tests, such as `echo "+new line" >> "$1"` don't work. It's obviously
  easy to work around it, but newline at EOF seems like a good practice
  anyway.
