CSS support for end when matching to upper block.

[envygeeks]

Right now we have CSS for the if/when/then and others but it would be nice if we could also CSS out the end too, so that it kind of matches the way that bracket-matcher works and makes it quite obvious what is going on if a user disables current line background.

if condition # Has CSS Class.
  work
end # Would love to have a CSS Class for this too.

My request isn't to highlight the end when I'm at the top, it's to have the end highlighted when I'm on the end and it's highlighting the top. Mine should be simple since you are already on that element. I read that one and assumed it was different since he wants the if to highlight the end, I want the end to be highlighted when the if is highlighted.
