Fixed a regression introduced in 0.29.0.gfm.2, where cmark-gfm would emit empty data-* attributes in HTML renderer, valid as HTML5, but invalid as XHTML.
I use cmark-gfm as part of my static site preprocessor and templating engine microsounds/kagami which I use for my personal website and while it's not explicitly stated as a requirement, I strive for XHTML5 compliance, a robust subset of XHTML and HTML5 as defined by W3C and WHATWG, and empty attribute syntax (attribute minimization) is invalid XHTML, preventing me from using my web browser's built in XHTML parser for strict syntax validation.
For context, this fixes issue #245
