Documentation needed: stdout.write line endings in management commands changed.

[xian@…]

This commit changed the default behavior of stdout.write() for management commands it add "\n" endings unless otherwise specified.
​https://github.com/django/django/commit/822d6d6dabc959532fb2904376580e8947c519f6

I haven't seen anything about this in the 1.5 documentation / changes and it requires code changes if you have any sort of output that relies on the old behavior.

Does the attached patch seem sufficient?

[xian@…]

I don't think it addresses the issue correctly. The fact that newlines are added is part of it, but I had to dig through the code to figure out how to _stop_ having newlines.

self.stdout.write("A message.\n") still works exactly the same after the change. But self.stdout.write("A message.") gets a \n tacked on.

The problem for me came because I was using self.stdout.write(".") to show progress on a single line like a progress bar. I had to replace that with: self.stdout.write(".", ending="") to fix it.

Mention the ending parameter

Is this one better?

Looks good to me, ship it :)
