This is still incorrect, as the \r\n (which $(echo . | tr \.\ '\015')
would emit) is interpreted correctly as a line break on Windows, meaning
that cr is now *empty*. Not what we want.

What I did is to replace the `cat` by `q_to_cr` (we have that lovely
function, might just as well use it), replace `${cr}` by `Q` and skip the
cr variable altogether.

Additionally, there is another huge problem: the "Applied autostash." is
printed to stdout, not stderr, in line with how things were done in the
shell version of rebase -i.

While this was just a minor bug previously, now we exercise that bug, by
redirecting stderr to stdout and redirecting stdout to the file `actual`.
Nothing says that stderr should be printed to that file before stdout, but
that is exactly what the test case tries to verify.

There is only one slight problem: in my Git for Windows SDK, stdout is
printed first.

The quick fix would be to redirect stderr and stdout independently.

However, I think it is time for that bug to be fixed: autostash messages
should really go to stderr, just like the rest of them rebase messages.

I attached the patch, together with the two fixups to Phillip's patches,
and a fixup for the autostash-messages-to-stderr patch that I think should
be squashed in but I really ran out of time testing this.

Phillip, would you mind picking those changes up as you deem appropriate?

Ciao,
Dscho

Subject: [PATCH 1/4] sequencer: print autostash messages to stderr

The rebase messages are printed to stderr traditionally. It was a bug
introduced in 587947750bd (rebase: implement --[no-]autostash and
rebase.autostash, 2013-05-12) and that bug has been faithfully copied
when reimplementing parts of the interactive rebase in the sequencer.

It is time to fix that: let's print the autostash messages to stderr
instead of stdout.

This is the companion to the proposed patch, but I had no time to verify
that the test suite still passes (it may actually test for the buggy
behavior...)
