I considered that, and I'm not against either highlighting parens or
the indentation. I chose to hack the former case because I couldn't
think of a pleasing way to highlight the indentation. For example:
what to highlight when c is against the left margin? Is there a way to
put something visual in between characters? Like a colored dot or
little line?
