I suspect the problem lies with Eric4, Notepad++ and Gedit. Do you
perhaps have to manually tell them that the file uses Windows line
separators?
I recommend opening the file in a hex editor and seeing for yourself what
line separators are used.

I don't think it is. Behaviour is a little different between Python 2 and
3, but by default, Python uses "Universal Newlines". When you open a file
in text mode, arbitrary line separators should be automatically
translated to \n when reading, and \n will be automatically translated to
os.line_sep when writing.
