I’ve got links in my site that are DOIs, such as:
[doi:10.1007/978-94-017-8542-6_1](http://dx.doi.org/10.1007/978-94-017-8542-6_1)
When Hugo’s markdown conversion happens, this gets converted into this:
<a href="http://dx.doi.org/10.1007/978-94-017-8542-6_1">doi:10.<sup>1007</sup>⁄<sub>978</sub>-94-017-8542-6_1</a>
How do I prevent this?
