  three patches that clean up white space:
  ws.patch.02.strings:
    Breaks strings that span lines into concatenated strings. I am not sure
    if you like this one. Other code works with concatenated strings, though.
  ws.patch.03.trailing:
    This removes trailing whitespace. No changes resulted from this for
    my setup.
  ws.patch.04.leading:
    This replaces space runs at the start of line with tabs. No changes
    again.
