[O] babel properties and inheritance

[Ken Mankoff]

Hi Org List,

I'm confused about the inheritance behavior of babel properties.

>From the MWE below, I'd expect :tangle to take effect at the heading level (it

  -k.

MWE ======================================================

#+PROPERTY: header-args: :tangle debug.sh :tangle-mode (identity #o755) 
:comments org

#+BEGIN_SRC emacs-lisp :tangle no
;; (setq org-use-property-inheritance t)
;; (setq org-use-property-inheritance nil)
(org-version nil t)
#+END_SRC
#+RESULTS:
: Org mode version 9.1.13 (9.1.13-elpa @ /Users/kdm/.emacs.d/elpa/org-20180709/)

* Foo
:PROPERTIES:
:header-args: :tangle foo.sh

#+BEGIN_SRC sh
echo "foo code"
#+END_SRC

** Bar
