The #7 here should be a link to the issue/pr.

Still valid:

This is a difficult one - we have deliberately not rendered these messages to prevent them being distracting on the newsfeed. This would require a sort of partial render I guess?

[silverwind]

I think the expectance is they render the same as on the repo pages.

Ideally, I think commit title/message renderers could be abstracted to one shared function that is shared between renderings like on frontpage or actual repo page.

Also related, full URLs should also abbreviate to a #1 link in the feed (the white link color is a separate bug):

Different rendering context has different rendering behaviors.

Some contexts renders the "short patterns", some others don't.

We close issues that need feedback from the author if there were no new comments for a month. 🍵
