Syntax Highlighting of Markdown Fenced Code Blocks

What: Add this to your Sublime Text editor Markdown.tmLanguage

<dict>
  <key>name</key>
  <string>markup.raw.block.markdown</string>
  <key>begin</key>
  <string>^(~{3,})</string>
  <key>end</key>
  <string>^\1~*\n</string>
</dict>

Why?

Certain superset-Markdown converts (like kramdown) support denoting code blocks not only by indenting the code–a pain when copy-pasting code–but also by “fencing” the code blocks with 3 or more tildes:

Here is some code:

~~~~
def foo()
  bar!
end
~~~~

The Markdown language bundle does not support this (since it’s not real Markdown) and so you don’t get proper syntax highlighting. Until you add the above.
