It is copied from the magit status buffer for Emacs…

I did that – no effect.
And if I look at

(defun indent-for-tab-command (&optional arg)
      (or (not (eq (funcall indent-line-function) 'noindent))
          (when (or (<= (current-column) (current-indentation))
                    (not (eq tab-always-indent 'complete)))
              (funcall (default-value 'indent-line-function)))))

I do not see why it should now behave correctly
(the “called” funcall is outside “save-restriction – widen”)

Hm, with src/emacs –q &  and M-x load-file 
I get the result of the attached screenshot area. 

If 'make bootstrap' doesn't help, could you try a step-by-step 
instruction, or a video, or something?

In bash:
      ./configure --with-ns --without-makeinfo --with-gnutls=no
      src/emacs –q &

in Emacs_
      C-x C-f new.el RET
      Insert: “(defun foo ()” RET
      Insert: <2 spaces> “3)” RET
      C-x SPC  C-p  C-x n n (enable narrowing with  SPC)
      (region still active) TAB -> works (i.e., no deletion of the spaces)
      (region no longer active) TAB -> deletes the 2 spaces (wrong as before)
