Sure! Unless it's time-critical to get this done. My spare time
varies, but if I can do it in my own tempo, I can surely look into
it. :)

I've already spotted out js-mode as a candidate to make use of the new
code. It's currently borrowing comment filling code from cc-mode,
which results in bugs such as #19399.
