As I mentioned in part two of my proposal, you could choose to store a
second property on a file that indicated what line ending it has in the
repository, but that would still be a property that only the client would
use. It isn't required, but it may be more efficient.

I was thinking of "remember", perhaps in the entries file? Except that
integrates it a little more into the client than may be desirable. In the
abstract, I was thinking more like a set of transforms (line endings,
keywords, whatever) that could be plugged in to a client or not depending
on user preference, and that would provide perhaps three callbacks
(transform_stream, reverse_transform_stream, requires_transform). In the
concrete, of course, that probably all goes out the window.

Me too. I'd given up on posting anything more on the topic, but thought
these clarifications might be helpful.
