visually connect matching brackets in gutter

Hi, there are several topics on matching brackets, but - unless i missed it - i haven't seen anyone proposing this: connect the matching brackets visually with a line in the gutter.. this is _very_ helpfull if brackets span a bit more than just a few lines. Here's a screenshot of how jEdit does it: http://dl.dropbox.com/u/10220684/screenshots/jedit_matching_brackets_ruler.png

thx for listening,
Jan
