I think a per-buffer history for goto-line makes sense, but I was also
wondering whether read-number should have its own separate history, too.

This would, I think, not interoperate well with that (that is, if
`read-number' passes a different variable to read-from-minibuffer than
nil).

So I think a better solution would be to fix the problem with
buffer-local variables not working in read-from-minibuffer first, and
then we could extend read-number with a history parameter instead of
hacking around the problem this way.
