Hello.

Just noticed that example block headings wrapping code evaluation
results appear downcased (arrows added):

#+RESULTS:
#+begin_example <=
... some result...
#+end_example   <=

In ob-core.el, line 2438 there's a "hidden" variable that controls
wether the headings appear upcased:
‘org-babel-capitalize-example-region-markers’. Setting it to non-nil
seems to solve the "problem".

Shouldn't this variable be public through the customize interface?

Also, it seems "capitalize" is the wrong verb here?
