Well, yes, different clients handle this in different ways. MacCVS Pro
had an option for converting line endings automatically. Of course, the
concept of "native" line endings is a big fuzzy these days, what with
MacOS X and Cygwin using LF endings, and decent text editors being able
to handle all three conventions.
Still though, the unix-native cvs command-line client, which is what
the vast majority of CVS users use, wants LF endings. It would be silly
not to produce them.

Yeah, that's ugly.

Can't the Windows CVS client be configured not to convert? But yes, we
need something better.
