Some PR's only change generated HTML

[maueroats]

PR #59 did not edit the source markdown, only the generated html. PR #71 only edits generated files.

This is going to be a problem next time somebody regenerates the files.

I would think think the policy should be only accept PR's that edit the markdown (possibly in addition to html?).

Do you want the html-only PR's backported to markdown? I think yes. Maybe I will take the time to clean up the issue.

The contributor's PR template could be adjusted to include a note about making sure to edit markdown.
