If I have a file with DOS line endings (e.g. \r\n) that I wrote on a Windows
box, then transferred that file to a Unix box and commited it with CVS, CVS
won't convert the line-endings to plain (\n).  When that happens, you end up
with \r\n line-endings on the CVS server, which is not supposed to happen.
Consequently, if you checkout (or update) with CVS from a Windows box, CVS will
obliviously replace the '\n' in '\r\n' with '\r\n', which will give you the
grand result of '\r\r\n'.
