Ooo that is really annoying. It looks like I can either have it not add to/extend a link at all when your cursor is at the end of a link, or I can have punctuation/a space terminate the link. Which makes more sense? Hopefully I explained that well.

Edit: I think I know what to do. I’m also going to look into adding community/user auto completing as you type their name in a comment. That’s something that’s missing that annoys me.
