Just open the file in 'text mode' (plain "r" or "w", as opposed to "rb"
or "wb") and everything on the code side just sees plain LF ('\n'), so
you only need to worry about detecting that.

In the file, on Windows, the CR ('\r') is added in silently when
writing, and removed again when reading (in text mode)
