How to get `Info-mode`'s text to horizontally fit the window like in the html version?

Question

See images for a comparison. The emacs version line-wraps much before the horizontal space ends. Html version was screenshotted from here

I believe the answer is that you can't (without a lot of work). Info text is hard-filled to a particular width (number of chars per line).

You can, however, use command text-scale-adjust, bound by default to C-x C-0, C-x C-=, C-x C--, C-x C-+, to zoom the text in or out, till it fits your window width as you like. Or press and hold Control while using the mouse wheel to do the same thing.

Or once you know the overall text-scaling factor you want, just use (text-scale-set FACTOR). You can put that in your init file, adding a function that does that to Info-mode-hook.
