Re: [PATCH v1 1/1] git diff --quiet exits with 1 on clean tree with CRLF conversions

All the solutions presented so far do cause a small change in behaviour
when using git diff --quiet: they may now cause warning messages like:

 warning: CRLF will be replaced by LF in crlf.txt.
 The file will have its original line endings in your working directory.

That is actually a good thing, I think.  As the test modifies a file
that originally has "Hello\r\nWorld\r\n" in it to this:

quoted

+test_expect_success 'quiet diff works on file with line-ending change that has no effect on repository' '
+	printf "Hello\r\nWorld\n" >crlf.txt &&

If you did "git add" at this point, you would get the same warning,
because the lack of CR on the second line could well be a mistake
you may want to notice and fix before going forward.  Otherwise
you'd be losing information that _might_ matter to you (i.e. the
fact that the first line had CRLF while the second had LF) and it is
the whole point of safe_crlf setting.

I also think it is a good thing if "git status" reported this path
as modified for the same reason (I didn't actually check if that is
the case).
