Yes, but not really.

It is not "warning" at all.  The users want to know when compared
contents do or do not end with an incomplete line at the end, and
the "\ No newline" is the diff's way to give that single bit of
information to us.

And the contents of a symbolic link typically is a single incomplete
line, so it is expected to see "\ No newline" when comparing them.

This is important as "git diff | git -C ../some/where/else apply"
should be able to recreate the change in the current repository
(which may have change to or addition of a symbolic link) in the
other repository, and "git apply" on the receiving end must be able
to tell that the symbolic link it needs to create in the other
repository must not have an extra LF at the end.
