Hello,  
I’d like to mark external links (links except from own domain) with an arrow through css.. Do I need to modify all es6 functions that parse links or is there simple way?

`if (DiscourseURL.isInternal(href))`

Also I’m not sure if this is definitive list of sources where links are parsed and styled

```
_showLinkCounts() in /app/assets/javascripts/discourse/widgets/post-cooked.js.es6
linkHtml(link) in app/assets/javascripts/discourse/widgets/post-links.js.es6 
html(attrs, state) in /app/assets/javascripts/discourse/widgets/topic-map.js.es6

```

Thanks in advance!
