It turned out to be more nuanced.

I can reproduce M-x (backward-char 1) behavior on emacs 24.3.1. So that's not
new. The new part shows only when the 'intangible property is set:

     
     (defun insert-with-fringe ()
       (interactive)
       (insert
        "      "
        (concat
         (propertize "fringe" 'display (list 'left-fringe 'filled-square font-lock-doc-face)
     		'intangible 'test)
         (propertize "dummy\n" 'display "AAA\n" 'font-lock-face font-lock-doc-face
     		'intangible 'test))
        "some more text")
       (previous-line))


Prior to 1st of April 2015 the (backward-char 1) used to work with the above
example. Something changed between 1st of April and 1st of June and as a
consequence the point is now stuck even with the above example. I wasn't able to
build emacs on commits between April 1st and June 1st.
