First of all, thanks for the info.

The current implementation of Git does an auto-detection
if a file is text or binary.

For a file which is "suspected to be text", it is expected to have either LF or CRLF as
line endings, but a "bare CR" make Git wonder:
Should this still be treated as a text file ?
If yes, should the CR be kept as is, or should it be converted into LF (or CRLF) ?

The current implementation may simply be explained by the fact that nobody has so far asked 
to treat this file as "text", so the implementation assumes it to be binary.

(Which makes the code a little bit easier, at the time it was written)

So the status of today is that you can force Git to let the CR as is,
when you specify that the file is "text".

Is there a real life problem behind it ?
And what should happen to the CRs ?
