It is really not that serious, and I strongly suggest drop
the new
warning. The same thing can happen if the DOS files are
committed
under Linux... I really saw such things happen when people
who were
supposed to work under Linux really copied files from
Windows machines
to Linux ones by scp (not FTP, which could correct the line
ending).

One must know what one is doing. `--lf' is not a default
option: when
one uses it, it is exactly like copying the file to a *NIX
machine and
doing things there. No one will blame you if he/she screwed
things.

A doubt here (cannot test right away): If I use `k+L' to
check out the
files, and I make the files into DOS line endings
accidentally, won't
the same things happen?

Best regards,

I tested `k+L' and confirmed it did *not* do what I want. I
want
something like `--lf': the checked-out files are like in a
UNIX
sandbox, both on check-out and on check-in (when there is
keyword
expansion). I want the files to remain in UNIX line endings.
Unfortunately this is not what `k+L' does.

So I would like to request making `--lf' have the old
behaviour, both
from the backward compatibility point of view, and from the
functionality point of view.
