Consider allowing LINK and META elements in HTML

[lucboudreau]

We would like this community to consider allowing the LINK and META HTML elements in GitHub markdown. As far as I can tell, they are not currently allowed.

These are necessary in order to add GMail message actions, as documented here. These links are very useful when the comments are generated by a system which uses the GitHub statuses API to validate commits and pull requests.

I'm not a HTML expert, so I will leave it to this group to discuss the implication of allowing those.

NB. We have also created an issue on the jch/html-pipeline project for this discussion to happen.

This repository is for the github-markup gem, a library which GitHub.com uses to choose a markup processor based on the type of the input data. All questions not related specifically to this gem should go to our support team. (Put another way: if a PR to this repo can't fix it, it doesn't belong here.)

I understand this is something that people want, but opening an issue here won't make that happen. People who work on the code that pertains to your query do not, in general, watch this repository. (I do because I maintain this gem.) To get it in front of their eyes, you'll need to go contact support so they can triage and prioritise it along with other requests.

Thanks for your understanding.
