Hi Seb,

This indentation is an HTML/CSS issue, as far as I can tell Org-mode is
generating the correct HTML.

The `org-src-preserve-indentation' variable only effects the indentation
of code *inside* of code blocks, it shouldn't have any effect on this
issue.

Github uses a ruby library named "org-ruby" to export, it is an entirely
separate export implementation.
