bug#38282: 26.3; goto-line should not share input history with other commands

I started working on this yesterday! My initial plan was to have a
separate history for `read-number', and then I thought that it might be
even better to have the history be buffer-local as well; because line
numbers from one buffer don't really make sense on another.

After I tried some stuff I came across a problem and posted it on the
Emacs SO:
https://emacs.stackexchange.com/questions/53892/buffer-local-input-history-for-read-from-minibuffer

It seems like `read-from-minibuffer' doesn't like having its HIST
parameter be buffer-local (but I may have misunderstood the problem).
I'm going to look into it more on depth these days.
