JShell /-n command

[Robert Field]

I agree this isn't useful and is confusing -- for another reason too -- 
from /help:

| /<id> -- re-run snippet by id
| /-<n> -- re-run n-th previous snippet

So /3 refers to a snippet-id and /-3 refers to a count backwards.

I've never used the /-n form.  For one, the up-arrow is much more 
convenient.

Unless I hear an strong advocate, I will remove.

Thanks,
Robert
