Looking at the code in read_minibuf, it does seem to access the
buffer-local value of the HIST variable, but my guess is that the buffer
it's looking at is the minibuffer?  And the variable isn't buffer-local
there.

There doesn't seem to be any way to tell read_minibuf what buffer it
should be looking at to get at the buffer-local value?
