[O] [beamer] Code blocks in lists?

[Sebastien Vauban]

Hello,

I've identified a couple of troubles related to code blocks inside lists (in
Beamer):

- code blocks break the list

- "relative" indentation of the code inside its frame is wrong except when
  code begins at column 0: is this a requirement?

- sometimes, "ORG-LIST-END-MARKER" is exported in PDF and in HTML.

Here is an ECM to show all of the above.

For the impatient, see 2 screenshots at http://i.imgur.com/2iiWq.png.

Best regards,
Seb

* Code in lists \\ Correct Org syntax

- This is an item

  This is some text to show how it's aligned...

  This is some extra text...

- This code block is properly indented in Org

  #+begin_src java
  if (test)
  {
      doit
  }
  #+end_src

  but *no correct relative indentation* in both PDF and HTML: see the code
  within its frame. There is a /left margin/ appended, not intended. Do I have
  to begin *all code blocks in column 0*?

- @Without this line@, there is a @bug@: output of =ORG-LIST-END-MARKER=.

* Code in lists \\ Workarounds?

- Weird indentation in Org

  #+begin_src java
if (test)
{
    doit
}
  #+end_src

  But *correct relative indentation* of the code (in PDF and HTML) in its frame.

- Wrong indentation in Org

#+begin_src java
if (test) {doit}
#+end_src

  Same (good) results regarding the relative indentation...

- In all cases, @putting code blocks seems to put an end to the list@
