Greetings, Org hackers!
I noticed that `dot' source blocks do not work out of the box: C-c C-c
works but C-c ' uses the Fundamental mode, even with the Graphviz MELPA
package installed.
This is because the major mode for the Dot language is `graphviz-dot'
and not `dot'. The attached patch improves the situation for the source
blocks defined as `#+BEGIN_SRC graphviz-dot', namely it makes C-c C-c
work with them.
P.S. As the next step, we could perhaps rename `ob-dot' to
`ob-graphviz-dot' and make `dot' the alias, not `graphviz-dot', so that
the officially documented `#+BEGIN_SRC dot' works out of the box too.

Subject: [PATCH] ob-dot: Add `graphviz-dot' language alias
* lisp/ob-dot.el: ("graphviz-dot"): Add `graphviz-dot' language alias
so that the `graphviz-dot-mode' from MELPA works out of the box (when
the source block uses `graphviz-dot' for the language).
