I agree that warning is needed if the setting says "warn".

Of course, it could become part of an irreversible action if you
did this:

	$ git commit ;# or whatever.  Now there is no local mods
        $ git apply <patch-1
	$ edit ;# to fix things up
        $ git apply <patch-2

and if you get the warning from patch-2.

But the safecrlf warning is primarily about a misdetection of
binaryness, so I do not think this sequence is not something we
would even want to worry about.
