Hello!

In the spirit of moving towards a more "modern" emacs, I'll address with
a patch the thing that actually confuses me personally the most.  Also,
it seems like an (dare I say it) uncontroversial change: set default
scroll value to 1.  It is mentioned as a small step towards the "smooth"
scrolling.  Is there some other places that needs to be updated?

Have a nice day!
Theodor Thornhill
