 At this point you should have tried mounting a directory on the *client*
in binmode, and adding a file from *that* directory. As it is, you seem to
have shown (both by adding files locally on the server and having no
problem, and by adding them remotely but to a known binmode fs and seeing
the problem) that you should be looking for something going wrong at the
client end. It might also be a useful experiment to try adding files from
the remote machine to the repository using the :pserver: protocol, to try
and establish if it's the SSh on the client machine that is underlying this
problem. If the problem still occurs using :pserver: suspect a bad
interaction with the textmode filesystem.
 Basically I think it's a bad idea to mount your filesystems in textmode
and then complain "But it keeps adding \r to my line endings". Accessing a
binary file through a textmode mountpoint is a dubious thing to expect to
work. I personally think the most reliable strategy is to accept that we're
working with a POSIX system, standardize on Unix EOLs throughout your files,
mount your filesystems in binary mode, and only ever have Unix<=>DOS EOL
conversions by deliberately invoking d2u/u2d manually.
