It's not super clear how far this recursion goes. For box subtree? A comment
would also help.

Acknowledged.

Why this change now? I don't recall having seen anyone request it in this
review. I think it was better the way it was in the previous patch set. It
carries out a very specific task, and doesn't deserve more than a static
function (that's what it used to be). No need to make it look like an API that
someone would want to call, IMHO. :)

I'm also working on crbug.com/563943 and found this will be needed by it.

[mstensho (USE GERRIT), 2015/12/03 20:41:57]

OK, fair enough. Then ignore me, but chrishtr has a point about commenting this,
though. :)

[Xianzhu, 2015/12/03 22:47:05]

Done.
