------- Additional Comments from Tony Gentilcore <tonyg at chromium.org>
I've re-implemented NestingLevelIncrementer in Document, but would like to
reuse the one in html/parser. If this patch is good, I can move
NestingLevelIncrementer somewhere where it can be shared either right before or
right after this patch.
