Unfurling-Safe Quine Write a proper quine containing at least one newline/linefeed whose every unfurling is either itself a proper quine or outputs the original quine. Your answer can mix and match outputting itself and outputting the original quine.

Unfurlings

Unfurlings consist of:


Appending spaces to make the input a rectangle.
Taking all lines above the bottom one and rotating them a quarter-turn clockwise about the lower-right corner so that the right edge is on the same level as the bottom edge.
Repeat step (2) until the string is a single line to find all unfurlings.


For example, the first unfurling of 

GFE
HID
ABC


is

   HG
   IF
ABCDE


and the rest are

   HG
   IF
ABCDE

     IH
ABCDEFG

       I
ABCDEFGH

ABCDEFGHI


This process is automated with this program adapted from Emigna's answer here,where each step of unfurling in the output is delimited by a dashed line.

Example

For example, if you have a program

K
AB


(no trailing spaces)

then it must be a proper quine and print itself('K\nAB', where \n represents a linefeed/newline).
According to the output of the unfurling program, we see that the next step in unfurling is 

  K
AB 


(note trailing space)

This must either print itself('  K\nAB ') or the original program ('K\nAB').
The next step in the unfurling is

AB K


This must either print itself ('AB K'), or the original program('K\nAB').

The byte-count of this program is 4 (K, \n, A, B).

Score

This is code-golf, so the shortest answer in bytes wins. Standard loopholes apply, as usual.

I mean, it works :p
