Making README more gentle to rookie Emacs users

[johanrosenkilde]

I went through the README and tried to make it more gentle and giving a better exemplification of what sage-shell-mode is good for. Some of it is similar to the landing page of sage-mode (which I wrote), but sage-shell-mode had much more complete technical documentation than sage-mode. I think the combination retains its informativeness while making it nicer for novice Emacs users.

Thanks! This is very helpful. Your English is much better than mine. Here are a few remarks.

• You don't have to require sage-shell-mode if you installed it by package.el. Most packages use autoload. I will fix it after merging.
• The ipython5.0 branch is getting old. Could you send a pull request to fix-branch next time? devel branch also exits but I have not used it for long time.

Anyway, thank you very much.

Cool, thanks for merging. Sure - I'll use fix-branch next time.

I thought that require was necessary when you want to e.g. add a hook (as in the eldoc example). That's not the case?

add-hook defines a global variable if the hook is not defined. So add-hook works well with autoload.

Ah, OK. Surely there'll be other cases where the require is necessary, but as long as none of the commands suggested in the help file need it, I guess it can just be removed :-)
