Well... shouldn't be that much of a problem? Putting this tr command in
the pipe should help:

    tr '\r' '\n'

A bigger issue may be that output is buffered when writing into a pipe,
which means you only get rsync's output when the buffer is full. This is
referred to in (long-standing) Debian bug #48108 (see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=48108).
