Superscript/Subscript Implementation in Markdown (BB-8686)
I'd like to propose the addition of superscripts and subscripts to the flavour of markdown the Bitbucket uses. Since Bitbucket uses python-markdown, there's a plugin to enable superscripts with the markdown syntax of ^<superscript>^.
I'd suggest implementing subscripts as ^^<subscript>^^. Subscripts and superscripts are supported with Creole as the markup for wiki pages, but that support isn't there for markdown. It would really aid with writing technical wikis with footnotes.
