And what I'm saying is that a completion table which handles quoting
such as read-file-name-internal returns file names which are partly
taken from the completion input and partly from the file-system.
So, what you perceive as "changing the case" is no change at all, it's
just that the string you expect to come from the file-system actually
comes from the user's input.

And again, "should" only in the sense that it's better, not that it's
needed for correctness.
