Done: https://issues.apache.org/jira/browse/SVN-4620

Not, it does not. Just created a repo on Windows 10. All internal files
are LF line ending.

I am not sure that I really understand the question. It shouldn't be any
different for different binaries on the same OS as long as you don't
have defines which change the behavior at runtime. Are there any?
Isn't it worth to file any issue which makes Subversion to able to read
repos in either file encoding but write only Unix style?
