Org BABEL plantuml bug--mindmap mode

[Spenser Truex <lists@spensertruex.com>]

PlantUML has an "org-compatible" outlining mode to generate graphical tree
images. It is ironically not org /babel/ compatible, since org does not like
having lines starting with =*= in a source code block.

* Reproduction:

** Install instructions
1. Add config to your init.
#+begin_src emacs-lisp
(require 'plantuml-mode) ;Must install first.
(plantuml-set-exec-mode "server")
#+end_src


** Observe the bug
Put your cursor in this block and run =org-babel-execute maybe=. It will
not execute.


#+begin_src plantuml :file "~/aphids-are-plant-bugs.png"
@startmindmap
* This is weird
** It does not work
*** If you have bullet fonts on, they go all wonky.
*** Org thinks this stuff inside is not plantuml.
*** Cannot even do a src edit command.
@endmindmap
#+end_src
