Why do we need to put this in vc-annotate rather than in vc-svn.el?

Because it's vc-annotate that commits the crime in the first place:
(with-output-to-temp-buffer temp-buffer-name
(let ((backend (or vc-bk (vc-backend file)))
(coding-system-for-read buffer-file-coding-system))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Any command running on MS-Windows should be expected to produce a CRLF
output, so inheriting EOL decoding from the buffer is not a good idea.

So you're saying that it's not just "svn annotate" that does that but
(e.g.) "git annotate" does it as well? If so, please clarify the
comment to explain that "svn annotate" is just one example.
