Win32 Perl + Subversion line break hell

News to me: when Perl writes to a file handle on Win32, it replaces LF with CRLF unless you explicitly call binmode on the file handle. In addition to that, Subversion's "native" setting for eol-style does the same.

To switch SVN over to LF only:
svn propset svn:eol-style LF <filename>
