What's the meaning of "literally" when a display table
element is [#xA0]?
Before Emacs 23, the character #xA0 represents the byte
0xA0. But now it is a character representing a Unicode
character U+00A0, and #x3FFFA0 is the character representing
the byte 0xA0.
And, to "display characters literally", we have been encoded
characters by the terminal coding system. Before Emacs 23,
the encoded result of #xA0 is always the byte 0xA0, but now
it depends on the terminal coding system.

I don't know. I didn't modify those part when I merged
unicode branch. I should have investigated the semantics of
display table at that time.
