Looks like someone wrote a nice bookmarklet that does what I was doing by hand. Its called GMapToGPX. It does indeed output a proper “trk” section (if you click on “Track”) for the point-by-point directions. Nice!

I’ve been using this great tool for a year or two now.
I don’t know if you realize it, but it even updates itself!
