Turn off reference style links in derobins' wmd

Question

I'm using the SO (derobins) version of wmd in a project and I'd like to be able to turn off the reference style linking.

Basically, I'd like to turn off linking where:

[an example][id] 

is a link, with the id being listed at the end of the entry, and instead use the simpler

[This link](http://example.net/)

syntax by default.
