command to restart the REPL without killing the buffer

[boehm-s]

A while ago, I answered this question, and I think the command could be useful to other users.

I'm not experimented at all in elisp, so I'm open to all kind of suggestions,

Cheers

Thank you for your PR!
I think it is better to introduce nodejs-repl-use-global custom variable so that .clear command clears the current context. The current implementation sets useGlobal to true as node CLI REPL does.
cf. https://nodejs.org/api/repl.html#repl_repl_start_options

What do you think?

% node -e "require('repl').start({ replMode: 'magic', useGlobal: true })"
> let foo = 1;
undefined
> .clear
> let foo = 2;
TypeError: Identifier 'foo' has already been declared
> 
% node -e "require('repl').start({ replMode: 'magic', useGlobal: false })"
> let foo = 1;
undefined
> .clear
Clearing context...
> let foo = 2;
undefined

I haven't tought about that, it's way better, and cleaner for sure !

Do you think it's OK like that ?

repl.start has two signatures, one is repl.start(options) and another is repl.start(prompt, stream, eval, useGlobal, ignoreUndefined, replMode). If you specify a object as the first argument, other arguments are ignored, so please change the code like below:
