I'm confused.

First, if the client applies any transformation at all to property
values, that'd be a bug. Property values are opaque octet sequences,
just like file contents, so they must be emitted verbatim. It so
happens that values of svn:* properties are UTF-8 with LF line endings,
so that's what Python should see, regardless of the local encoding and
EOL style.

For the same reason, I'd have expected the expected output to be given
as bytes objects rather than as str objects.

Second, where is the 'last \n' that the comment refers to? I don't see
it in the code. I wouldn't expect a trailing newline to be emitted,
either, since svnadmin.tests.check_prop() passes --strict, which is
documented as a deprecated alias to --no-newline.

Thanks!

Daniel
