  I tried gdbreplay yesterday, but the remotelogfile I received was made
on Windows, so the lines were terminated with \r\n rather than plain
\n.

This patch changes gdbreplay to allow \r or \r\n line termination when
reading the log file.

I'm okay with treating \r\n as a single \n, but do we really want to
treat a single \r as if it were \n?  I thought systems which used that
EOL convention are not really widespread, to say the least.

Thanks.
