The new pathlib.Path [read|write]_[binary|text] methods will be very useful, one thing I miss badly is the newline argument for write_text.

In some cases text files need a specific line ending (independent from the platform the code is being executed on.) In my mind this is analogous to passing an explicit encoding argument.

Of course, one can always use built-in open for this scenario. It would be a nice addition anyway :)
