I agree overall. It's hard to know for sure if a web page will look ok 
in readable mode without trying it first.

That's why I opted to keep the default behavior unchanged in my patch. 
It just makes it possible to add 'eww-readable' to 
'eww-after-render-hook' without producing duplicate history entries. 
That way, if most of the pages you visit *are* readable, you can set it 
up like that and still get to the full view by calling 'eww-readable' again.

Yeah, I think I might add that in, since 1) I'd find it useful, 2) it 
should be easy, and 3) the Safari browser already supports this, so 
there's already precedent elsewhere. (It's arguably even more relevant 
for EWW than Safari, since many webpages are a real mess in EWW without 
readable-mode.)
